chore(3p/git): Unvendor git and track patches instead r/2903

This was vendored a long time ago under the expectation that keeping
it in sync with cgit would be easier this way, but it has proven not
to be a big issue.

On the other hand, a vendored copy of git is an annoying maintenance
burden. It is much easier to rebase the single (dottime) patch that we
have.

This removes the vendored copy of git and instead passes the git
source code to cgit via `pkgs.srcOnly`, which includes the applied
patch so that cgit can continue rendering dottime.

-GIT v1.5.2 Release Notes
-========================
-
-Updates since v1.5.1
---------------------
-
-* Plumbing level superproject support.
-
-  You can include a subdirectory that has an independent git
-  repository in your index and tree objects of your project
-  ("superproject").  This plumbing (i.e. "core") level
-  superproject support explicitly excludes recursive behaviour.
-
-  The "subproject" entries in the index and trees of a superproject
-  are incompatible with older versions of git.  Experimenting with
-  the plumbing level support is encouraged, but be warned that
-  unless everybody in your project updates to this release or
-  later, using this feature would make your project
-  inaccessible by people with older versions of git.
-
-* Plumbing level gitattributes support.
-
-  The gitattributes mechanism allows you to add 'attributes' to
-  paths in your project, and affect the way certain git
-  operations work.  Currently you can influence if a path is
-  considered a binary or text (the former would be treated by
-  'git diff' not to produce textual output; the latter can go
-  through the line endings conversion process in repositories
-  with core.autocrlf set), expand and unexpand '$Id$' keyword
-  with blob object name, specify a custom 3-way merge driver,
-  and specify a custom diff driver.  You can also apply
-  arbitrary filter to contents on check-in/check-out codepath
-  but this feature is an extremely sharp-edged razor and needs
-  to be handled with caution (do not use it unless you
-  understand the earlier mailing list discussion on keyword
-  expansion).  These conversions apply when checking files in
-  or out, and exporting via git-archive.
-
-* The packfile format now optionally supports 64-bit index.
-
-  This release supports the "version 2" format of the .idx
-  file.  This is automatically enabled when a huge packfile
-  needs more than 32-bit to express offsets of objects in the
-  pack.
-
-* Comes with an updated git-gui 0.7.1
-
-* Updated gitweb:
-
-  - can show combined diff for merges;
-  - uses font size of user's preference, not hardcoded in pixels;
-  - can now 'grep';
-
-* New commands and options.
-
-  - "git bisect start" can optionally take a single bad commit and
-    zero or more good commits on the command line.
-
-  - "git shortlog" can optionally be told to wrap its output.
-
-  - "subtree" merge strategy allows another project to be merged in as
-    your subdirectory.
-
-  - "git format-patch" learned a new --subject-prefix=<string>
-    option, to override the built-in "[PATCH]".
-
-  - "git add -u" is a quick way to do the first stage of "git
-    commit -a" (i.e. update the index to match the working
-    tree); it obviously does not make a commit.
-
-  - "git clean" honors a new configuration, "clean.requireforce".  When
-    set to true, this makes "git clean" a no-op, preventing you
-    from losing files by typing "git clean" when you meant to
-    say "make clean".  You can still say "git clean -f" to
-    override this.
-
-  - "git log" family of commands learned --date={local,relative,default}
-    option.  --date=relative is synonym to the --relative-date.
-    --date=local gives the timestamp in local timezone.
-
-* Updated behavior of existing commands.
-
-  - When $GIT_COMMITTER_EMAIL or $GIT_AUTHOR_EMAIL is not set
-    but $EMAIL is set, the latter is used as a substitute.
-
-  - "git diff --stat" shows size of preimage and postimage blobs
-    for binary contents.  Earlier it only said "Bin".
-
-  - "git lost-found" shows stuff that are unreachable except
-    from reflogs.
-
-  - "git checkout branch^0" now detaches HEAD at the tip commit
-    on the named branch, instead of just switching to the
-    branch (use "git checkout branch" to switch to the branch,
-    as before).
-
-  - "git bisect next" can be used after giving only a bad commit
-    without giving a good one (this starts bisection half-way to
-    the root commit).  We used to refuse to operate without a
-    good and a bad commit.
-
-  - "git push", when pushing into more than one repository, does
-    not stop at the first error.
-
-  - "git archive" does not insist you to give --format parameter
-    anymore; it defaults to "tar".
-
-  - "git cvsserver" can use backends other than sqlite.
-
-  - "gitview" (in contrib/ section) learned to better support
-    "git-annotate".
-
-  - "git diff $commit1:$path2 $commit2:$path2" can now report
-    mode changes between the two blobs.
-
-  - Local "git fetch" from a repository whose object store is
-    one of the alternates (e.g. fetching from the origin in a
-    repository created with "git clone -l -s") avoids
-    downloading objects unnecessarily.
-
-  - "git blame" uses .mailmap to canonicalize the author name
-    just like "git shortlog" does.
-
-  - "git pack-objects" pays attention to pack.depth
-    configuration variable.
-
-  - "git cherry-pick" and "git revert" does not use .msg file in
-    the working tree to prepare commit message; instead it uses
-    $GIT_DIR/MERGE_MSG as other commands do.
-
-* Builds
-
-  - git-p4import has never been installed; now there is an
-    installation option to do so.
-
-  - gitk and git-gui can be configured out.
-
-  - Generated documentation pages automatically get version
-    information from GIT_VERSION.
-
-  - Parallel build with "make -j" descending into subdirectory
-    was fixed.
-
-* Performance Tweaks
-
-  - Optimized "git-rev-list --bisect" (hence "git-bisect").
-
-  - Optimized "git-add $path" in a large directory, most of
-    whose contents are ignored.
-
-  - Optimized "git-diff-tree" for reduced memory footprint.
-
-  - The recursive merge strategy updated a worktree file that
-    was changed identically in two branches, when one of them
-    renamed it.  We do not do that when there is no rename, so
-    match that behaviour.  This avoids excessive rebuilds.
-
-  - The default pack depth has been increased to 50, as the
-    recent addition of delta_base_cache makes deeper delta chains
-    much less expensive to access.  Depending on the project, it was
-    reported that this reduces the resulting pack file by 10%
-    or so.
-
-
-Fixes since v1.5.1
-------------------
-
-All of the fixes in v1.5.1 maintenance series are included in
-this release, unless otherwise noted.
-
-* Bugfixes
-
-  - Switching branches with "git checkout" refused to work when
-    a path changes from a file to a directory between the
-    current branch and the new branch, in order not to lose
-    possible local changes in the directory that is being turned
-    into a file with the switch.  We now allow such a branch
-    switch after making sure that there is no locally modified
-    file nor un-ignored file in the directory.  This has not
-    been backported to 1.5.1.x series, as it is rather an
-    intrusive change.
-
-  - Merging branches that have a file in one and a directory in
-    another at the same path used to get quite confused.  We
-    handle such a case a bit more carefully, even though that is
-    still left as a conflict for the user to sort out.  This
-    will not be backported to 1.5.1.x series, as it is rather an
-    intrusive change.
-
-  - git-fetch had trouble with a remote with insanely large number
-    of refs.
-
-  - "git clean -d -X" now does not remove non-excluded directories.
-
-  - rebasing (without -m) a series that changes a symlink to a directory
-    in the middle of a path confused git-apply greatly and refused to
-    operate.
