[CI:BUILD] rpm: hard dependency on gvisor-tap-vsock-gvforwarder

With containers/gvisor-tap-vsock#268,
gvforwarder is now provided via the subpackage
`gvisor-tap-vsock-gvforwarder`. FCOS needs this gvforwarder, hence the
hard dependency.

This change is only intended for f38 and higher.

[NO NEW TESTS NEEDED]
