Test advertised capabilities with protocol V0 and allow*Sha1InWant

The advertised capabilities with protocol V0 were untested
leading to potential regressions when advertising what
SHA1 should or should not be on the list of capabilities.

Verify that allow-tip-sha1-in-want and allow-reachable-sha1-in-want
are properly advertised with the allow*Sha1InWant is set in
jgit.config.
