Subject: selftests/mm: fix invocation of tests that are run via shell scripts
Date: Fri, 2 Jun 2023 19:15:51 -0700

We cannot depend upon git to reliably retain the executable bit on shell
scripts, or so I was told several years ago while working on this same
run_vmtests.sh script. And sure enough, things such as test_hmm.sh are
lately failing to run, due to lacking execute permissions.

Fix this by explicitly adding "bash" to each of the shell script
invocations. Leave fixing the overall approach to another day.
