Make scripts/checkpatch.pl output a 'CHECK' advertising any test suites
proposed for the changed subsystems, and prompting their execution.
Using 'CHECK', instead of 'WARNING', or 'ERROR', because test suite
commands executed for testing can generally be off by an option/argument
or two, depending on the situation, while still satisfying the
maintainer requirements, but failing the comparison with the V: entry
and raising alarm unnecessarily.
However, see the later patch adding the proposal strength to the V:
entry and allowing raising the severity of the message for those who'd
like that.
