copr: Also install git

[cgwalters]

This whole "install all the build tools to make a source rpm" flow rather stinks...

One thing that would help is for me (or someone else) to package cargo-vendor-filterer at some point.

LGTM

OK well, that improved things but maddeningly enough it's still broken and the reason appears to be that the make srpm process runs in a f39 root. Why is it using f39? Well, there's all sorts of mock/copr magic going on there. The thing is, this would all be so much more obvious if building the SRPM just ran in a standard container image.

You can reproduce this build on your computer by running:

  sudo dnf install copr-rpmbuild
  /usr/bin/copr-rpmbuild --verbose --drop-resultdir --srpm --task-url https://copr.fedorainfracloud.org/backend/get-srpm-build-task/7698092

I mean yeah but, why can't I reproduce it with podman run?

OK anyways trying #664
