[PATCH tip/core/rcu 26/32] tools/memory-model: Make history-check scripts use mselect7

The history-check scripts currently use grep to ignore non-C-language
litmus tests, which is a bit fragile. This commit therefore enlists the
aid of "mselect7 -arch C", given Luc Maraget's recent modifications that
allow mselect7 to operate in filter mode.

This change requires herdtools 7.52-32-g1da3e0e50977 or later.
