[CI:BUILD] Packit: show SHORT_SHA in podman --version for COPR builds

This change will allow `podman --version` from COPR rpm builds to be of
the form `X.Y.Z-dev-SHORT_SHA`.

Also specify a `copr_build` macro as it feels more intuitive
than `copr_username` or `copr_project`.

[NO NEW TESTS NEEDED]
