crossdev: remove the repos.conf entry for the output overlay during uninstall

If the output overlay is completely removed during uninstall, it is
incorrect to leave behind the repos.conf file since the location
specified in the conf file points to a non-existing directory.

We scan all the conf files under ${CONFIGROOT}/repos.conf, looking for
the file that defines the output overlay and remove it if it is
managed by crossdev.
