[PATCH] tests: handle NO_PYTHON setting

[Jeff King <peff@peff.net>]

Without this, test-lib checks that the git_remote_helpers
directory has been built. However, if we are building
without python, we will not have done anything at all in
that directory, and test-lib's sanity check will fail.

On top of sr/vcs-helper.

This feels a little funny for NO_PYTHON to mean "no remote helpers at
all". But that is the way the Makefile is set up, since we seem to have
only python helpers.
