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.

-TL;DR: Run update_unicode.sh after the publication of a new Unicode
-standard and commit the resulting unicode-widths.h file.
-
-The long version
-================
-
-The Git source code ships the file unicode-widths.h which contains
-tables of zero and double width Unicode code points, respectively.
-These tables are generated using update_unicode.sh in this directory.
-update_unicode.sh itself uses a third-party tool, uniset, to query two
-Unicode data files for the interesting code points.
-
-On first run, update_unicode.sh clones uniset from Github and builds it.
-This requires a current-ish version of autoconf (2.69 works per December
-2016).
-
-On each run, update_unicode.sh checks whether more recent Unicode data
-files are available from the Unicode consortium, and rebuilds the header
-unicode-widths.h with the new data. The new header can then be
-committed.
