test_slru: Fix LWLock tranche allocation in EXEC_BACKEND builds.
Currently, test_slru's shmem_startup_hook unconditionally generates
new LWLock tranche IDs. This is fine on non-EXEC_BACKEND builds,
where only the postmaster executes this hook, but on EXEC_BACKEND
builds, every backend executes it, too. To fix, only generate the
tranche IDs in the postmaster process by checking the
IsUnderPostmaster variable.
This is arguably a bug fix and could be back-patched, but since the
damage is limited to some extra unused tranche IDs in a test
module, I'm not going to bother.
