Subject: test: reduce number of threads to 32 in LibCephFS.ShutdownRace

test: reduce number of threads to 32 in LibCephFS.ShutdownRace

We're still occasionally hitting file descriptor limits when running
this test. Reduce the thread count to 32 for now, since it was possible
to reproduce the original problem with 10 or so threads.
