core: Avoid warning about valid OCHP commands

It's ok to have an OCHP command, so long as we can find it.

lib/test-runcmd: Add anomaly detection for semi-colons

They're "job control" issues and must be properly detected

someone failed at shell-scripting, so we may as well have the
test in place.
