ptserver: Remove duplicate ubik_SetLock in listSuperGroups
It looks like a call to ubik_SetLock(.. LOCKREAD) was left in
place in listSuperGroups after locking was moved to ReadPreamble
in commit
a6d64d70 (ptserver: Refactor per-call ubik initialisation)
When compiled with 'supergroups', and once contacted by
"pts mem -expandgroups ..", ptserver will therefore abort() with
Ubik: Internal Error: attempted to take lock twice
This patch removes the superfluous ubik_SetLock.
