tools/memory-model: Convert underscores to hyphens

Typical cat-language code uses hyphens for word separators in
identifiers, but several LKMM identifiers use underscores instead.
This commit therefore converts underscores to hyphens in the .bell-
and .cat-file identifiers corresponding to smp_mb__before_atomic(),
smp_mb__after_atomic(), and smp_mb__after_spinlock().
