glusterfs: Patch upstream bug preventing glusterfind from running.

See: https://bugzilla.redhat.com/show_bug.cgi?id=1489610

Also add patch to correctly log stderr from remote nodes
when glusterfind fails.
This, too, should be removed when fixed upstream.

(cherry picked from commit e7325f82a32cea8d7e6cfafff9e61e4468fd19dc)
