Revert "hound: use updated git packages"

This reverts commit 3f2cc870b8.

Upstream Debian has updated git to 2.30.2-1+deb11u1 which patches git
for the issues we manually patched to cover. We don't need the manual
patch anymore and can switch to the distro hence this revert.

Reviewers should double check that the image build process installs the
expected 2.30.2-1+deb11u1 version.
