Lubomír Sedlář f7a9c77626 ostree: Add notification handler to wait for signature
This script can be used as a notification handler. For most messages it
does nothing, but when it sees a new commit in an ostree repo, it will
wait for a signature of the new commit to appear.

This is useful for building images later so that they include the
signature as well.
