btrfs-progs: tests: return metadata_uuid or fsid as per METADATA_UUID flag 

Previous commit "btrfs-progs: dump-super: print actual metadata_uuid
value" changed the value of the super_block::metadata_uuid to be printed
as it is, without tweaking it depending on the METADATA_UUID flag.

Apply similar tweak in the common helper functions used to read the
metadata_uuid so that test-cases still be successful.
