tools/memory-model: Split runlitmus.sh out of checklitmus.sh
This commit prepares for adding --hw capability to github litmus-test scripts by splitting runlitmus.sh (which simply runs the verification) out of checklitmus.sh (which also judges the results). Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
