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 v2.15.1 Release Notes
-=========================
-
-Fixes since v2.15
------------------
-
- * TravisCI build updates.
-
- * "auto" as a value for the columnar output configuration ought to
-   judge "is the output consumed by humans?" with the same criteria as
-   "auto" for coloured output configuration, i.e. either the standard
-   output stream is going to tty, or a pager is in use.  We forgot the
-   latter, which has been fixed.
-
- * The experimental "color moved lines differently in diff output"
-   feature was buggy around "ignore whitespace changes" edges, which
-   has been corrected.
-
- * Instead of using custom line comparison and hashing functions to
-   implement "moved lines" coloring in the diff output, use the pair
-   of these functions from lower-layer xdiff/ code.
-
- * Some codepaths did not check for errors when asking what branch the
-   HEAD points at, which have been fixed.
-
- * "git commit", after making a commit, did not check for errors when
-   asking on what branch it made the commit, which has been corrected.
-
- * "git status --ignored -u" did not stop at a working tree of a
-   separate project that is embedded in an ignored directory and
-   listed files in that other project, instead of just showing the
-   directory itself as ignored.
-
- * A broken access to object databases in recent update to "git grep
-   --recurse-submodules" has been fixed.
-
- * A recent regression in "git rebase -i" that broke execution of git
-   commands from subdirectories via "exec" instruction has been fixed.
-
- * "git check-ref-format --branch @{-1}" bit a "BUG()" when run
-   outside a repository for obvious reasons; clarify the documentation
-   and make sure we do not even try to expand the at-mark magic in
-   such a case, but still call the validation logic for branch names.
-
- * Command line completion (in contrib/) update.
-
- * Description of blame.{showroot,blankboundary,showemail,date}
-   configuration variables have been added to "git config --help".
-
- * After an error from lstat(), diff_populate_filespec() function
-   sometimes still went ahead and used invalid data in struct stat,
-   which has been fixed.
-
- * UNC paths are also relevant in Cygwin builds and they are now
-   tested just like Mingw builds.
-
- * Correct start-up sequence so that a repository could be placed
-   immediately under the root directory again (which was broken at
-   around Git 2.13).
-
- * The credential helper for libsecret (in contrib/) has been improved
-   to allow possibly prompting the end user to unlock secrets that are
-   currently locked (otherwise the secrets may not be loaded).
-
- * Updates from GfW project.
-
- * "git rebase -i" recently started misbehaving when a submodule that
-   is configured with 'submodule.<name>.ignore' is dirty; this has
-   been corrected.
-
- * Some error messages did not quote filenames shown in it, which have
-   been fixed.
-
- * Building with NO_LIBPCRE1_JIT did not disable it, which has been fixed.
-
- * We used to add an empty alternate object database to the system
-   that does not help anything; it has been corrected.
-
- * Error checking in "git imap-send" for empty response has been
-   improved.
-
- * An ancient bug in "git apply --ignore-space-change" codepath has
-   been fixed.
-
- * There was a recent semantic mismerge in the codepath to write out a
-   section of a configuration section, which has been corrected.
-
-Also contains various documentation updates and code clean-ups.
