classes: image_types_ostree: check OSTree repo existence using ostree

Currently we assume if the OSTree repo exists, that there is a
OSTree repo in it. This does not need to be true in general, and
when using lockfiles bitbake will create the directory before
the do_image_ostree task is executed the first time.

Use ostree refs to detect whether the target directory contains a
OSTree repo.
