Subject: selftests/mm: fix invocation of tests that are run via shell scripts
Date: Thu, 1 Jun 2023 18:33:51 -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.

A nice clean way to fix this would have been to use TEST_PROGS instead of
TEST_FILES for the .sh scripts here.  That tells the selftest framework to
run these (and emit a warning if the files are not executable, but still
run them anyway).

Unfortunately, run_vmtests.sh has its own run_test() routine, which does
*not* do the right thing for shell scripts.

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