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.

-=head1 NAME
-
-Git::LoadCPAN - Wrapper for loading modules from the CPAN (OS) or Git's own copy
-
-=head1 DESCRIPTION
-
-The Perl code in Git depends on some modules from the CPAN, but we
-don't want to make those a hard requirement for anyone building from
-source.
-
-Therefore the L<Git::LoadCPAN> namespace shipped with Git contains
-wrapper modules like C<Git::LoadCPAN::Module::Name> that will first
-attempt to load C<Module::Name> from the OS, and if that doesn't work
-will fall back on C<FromCPAN::Module::Name> shipped with Git itself.
-
-Usually distributors will not ship with Git's Git::FromCPAN tree at
-all via the C<NO_PERL_CPAN_FALLBACKS> option, preferring to use their
-own packaging of CPAN modules instead.
-
-This module is only intended to be used for code shipping in the
-C<git.git> repository. Use it for anything else at your peril!
-
-=cut
-
-# NO_PERL_CPAN_FALLBACKS_STR evades the sed search-replace from the
-# Makefile, and allows for detecting whether the module is loaded from
-# perl/Git as opposed to perl/build/Git, which is useful for one-off
-# testing without having Error.pm et al installed.
-use constant NO_PERL_CPAN_FALLBACKS_STR => '@@' . 'NO_PERL_CPAN_FALLBACKS' . '@@';
-use constant NO_PERL_CPAN_FALLBACKS => (
-	q[@@NO_PERL_CPAN_FALLBACKS@@] ne ''
-	and
-	q[@@NO_PERL_CPAN_FALLBACKS@@] ne NO_PERL_CPAN_FALLBACKS_STR

-BUG: The '%s' module is not here, but NO_PERL_CPAN_FALLBACKS was set!
-
-Git needs this Perl module from the CPAN, and will by default ship
-with a copy of it. This Git was built with NO_PERL_CPAN_FALLBACKS,
-meaning that whoever built it promised to provide this module.
-
-You're seeing this error because they broke that promise, and we can't
-load our fallback version, since we were asked not to install it.
-
-If you're seeing this error and didn't package Git yourself the
-package you're using is broken, or your system is broken. This error
-won't appear if Git is built without NO_PERL_CPAN_FALLBACKS (instead
-we'll use our fallback version of the module).
