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.

-## tar archive frontend for git-fast-import
-##
-## For example:
-##
-##  mkdir project; cd project; git init
-##  perl import-tars.perl *.tar.bz2
-##  git whatchanged import-tars
-##
-## Use --metainfo to specify the extension for a meta data file, where
-## import-tars can read the commit message and optionally author and
-## committer information.
-##
-##  echo 'This is the commit message' > myfile.tar.bz2.msg
-##  perl import-tars.perl --metainfo=msg myfile.tar.bz2
