git: upgrade 2.37.3 -> 2.38.1

Fixes CVE-2022-39260

Git v2.38.1 Release Notes
=========================

This release merges the security fix that appears in v2.30.6; see
the release notes for that version for details.

Excerpt from 2.30.6 release notes:

 * CVE-2022-39260:
   An overly-long command string given to `git shell` can result in
   overflow in `split_cmdline()`, leading to arbitrary heap writes and
   remote code execution when `git shell` is exposed and the directory
   `$HOME/git-shell-commands` exists.

   `git shell` is taught to refuse interactive commands that are
   longer than 4MiB in size. `split_cmdline()` is hardened to reject
   inputs larger than 2GiB.

Credit for finding CVE-2022-39260 goes to Kevin Backhouse of GitHub.
The fix was authored by Kevin Backhouse, Jeff King, and Taylor Blau.
