push: continue without locking on lock failure other than EEXIST (issue5882)

This code was added by 3f5e75c22585 "push: make locking of source optional
(issue3684)", but EACCES isn't the only error that could be triggered by
filesystem permission. I think catching LockUnavailable is more appropriate
than testing errno value by caller.
