Fix rabbit_vm:memory stream_queue_coordinator_procs always zero

The memory of rabbit_stream_coordinator process was reported as other,
because there was a mismatch in ancestors. It is not under
`ra_server_sup_sup` any more but:
`[_,ra_coordination_server_sup_sup,_,ra_systems_sup,ra_sup,_]`

Instead of ancestors use its registered name to categorize it.
