Currently, judgelitmus.sh treats use of unknown primitives (such as
srcu_read_lock() prior to SRCU support) as "!!! Verification error".
This can be misleading because it fails to call out typos and running
a version LKMM on a litmus test requiring a feature not provided by
that version. This commit therefore changes judgelitmus.sh to check
for unknown primitives and to report them, for example, with:
'!!! Current LKMM version does not know "rcu_write_lock"'.
