[PATCH 1/6] t5570: use ls-remote instead of clone for interp tests

[Jeff King <peff@peff.net>]

We don't actually care about the clone operation here; we
just want to know if we were able to actually contact the
remote repository. Using ls-remote does that more
efficiently, and without us having to worry about managing
the tmp.git directory.
