[PATCH tip/core/rcu 17/32] tools/memory-model: Make runlitmus.sh generate .litmus.out for --hw

In the absence of "Result:" comments, the runlitmus.sh script relies on
litmus.out files from prior LKMM runs. This can be a bit user-hostile,
so this commit makes runlitmus.sh generate any needed .litmus.out files
that don't already exist.
