ci: Add a flow that does a git libostree + git rust-bindings

In https://github.com/ostreedev/ostree/pull/2633 I realized
that our CI only builds git of libostree or git of rust-bindings,
not git of both.  And we definitely want to test the latter too,
so e.g. the Rust tests *also* become tests for changes to the C code.
