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.

-	   This trick arranges for messages to be emitted in the user's
-	   requested encoding, but avoids setting LC_CTYPE from the
-	   environment for the whole program.
-
-	   This primarily done to avoid a bug in vsnprintf in the GNU C
-	   Library [1]. which triggered a "your vsnprintf is broken" error
-	   on Git's own repository when inspecting v0.99.6~1 under a UTF-8
-	   locale.
-
-	   That commit contains a ISO-8859-1 encoded author name, which
-	   the locale aware vsnprintf(3) won't interpolate in the format
-	   argument, due to mismatch between the data encoding and the
-	   locale.
-
-	   Even if it wasn't for that bug we wouldn't want to use LC_CTYPE at
-	   this point, because it'd require auditing all the code that uses C
-	   functions whose semantics are modified by LC_CTYPE.
-
-	   But only setting LC_MESSAGES as we do creates a problem, since
-	   we declare the encoding of our PO files[2] the gettext
-	   implementation will try to recode it to the user's locale, but
-	   without LC_CTYPE it'll emit something like this on 'git init'
-	   under the Icelandic locale:
-
-	       Bj? til t?ma Git lind ? /hlagh/.git/
-
-	   Gettext knows about the encoding of our PO file, but we haven't
-	   told it about the user's encoding, so all the non-US-ASCII
-	   characters get encoded to question marks.
-
-	   But we're in luck! We can set LC_CTYPE from the environment
-	   only while we call nl_langinfo and
-	   bind_textdomain_codeset. That suffices to tell gettext what
-	   encoding it should emit in, so it'll now say:
-
-	       Bjó til tóma Git lind í /hlagh/.git/
-
-	   And the equivalent ISO-8859-1 string will be emitted under a
-	   ISO-8859-1 locale.
-
-	   With this change way we get the advantages of setting LC_CTYPE
-	   (talk to the user in his language/encoding), without the major
-	   drawbacks (changed semantics for C functions we rely on).
-
-	   However foreign functions using other message catalogs that
-	   aren't using our neat trick will still have a problem, e.g. if
-	   we have to call perror(3):
-
-	   #include <stdio.h>
-	   #include <locale.h>
-	   #include <errno.h>
-
-	   int main(void)
-	   {
-		   setlocale(LC_MESSAGES, "");
-		   setlocale(LC_CTYPE, "C");
-		   errno = ENODEV;
-		   perror("test");
-		   return 0;
-	   }
-
-	   Running that will give you a message with question marks:
-
-	   $ LANGUAGE= LANG=de_DE.utf8 ./test
-	   test: Kein passendes Ger?t gefunden
-
-	   The vsnprintf bug has been fixed since glibc 2.17.
-
-	   Then we could simply set LC_CTYPE from the environment, which would
-	   make things like the external perror(3) messages work.
-
-	   See t/t0203-gettext-setlocale-sanity.sh's "gettext.c" tests for
-	   regression tests.
-
-	   1. http://sourceware.org/bugzilla/show_bug.cgi?id=6530
