tools/memory-model/README: Update klitmus7 compat table

commit 5b759db441 upstream.

EXPORT_SYMBOL of do_exec() was removed in v5.17.  Unfortunately,
kernel modules from klitmus7 7.56 have do_exec() at the end of
each kthread.

herdtools7 7.56.1 has addressed the issue.

Update the compatibility table accordingly.
