Fix volumes with uid and gid options

Podman uses the volume option map to check if it has to mount the volume
or not when the container is started. Commit 28138dafcc39 added to uid
and gid options to this map, however when only uid/gid is set we cannot
mount this volume because there is no filesystem or device specified.
Make sure we do not try to mount the volume when only the uid/gid option
is set since this is a simple chown operation.

Also when a uid/gid is explicity set, do not chown the volume based on
the container user when the volume is used for the first time.

Fixes #10620
