Correct our usage of the bats run helper

The bats "run" helper function sets "$status", so there's no point to
checking the value of "$status" when we haven't used the "run" helper to
run a command, and we almost always want to be checking the value after
we have used the helper.

There's no need to run commands like 'sleep' or 'rm -f' with the helper,
since they're not expected to fail, and if they do, it's probably
indicative of a larger problem that we want to allow to cause tests to
fail.

Helper functions like start_crio already check "$status" when they call
"run", so we don't need to check it again after they return.
