qa: add a check_commands.sh script which looks for commands with no tests

This isn't run automatically by anything yet. Note that it's also a best-effort
thing; passing doesn't guarantee there are tests. It can be pretty easily fooled
if the command is a common word which shows up in specifying other things,
for instance.
