[PATCH 10/10 v2] ktest: Introduce FAILURE_LINE

[Andrew Jones <drjones@redhat.com>]

This is the counterpart to SUCCESS_LINE. In some cases the boot will
succeed, but the console will display a message that means that the
boot test failed (such as a warning) while it boots. Use this option
to detect this and fail the test.
