In order to show a friendlier error message that does not bury the
actual sanity error in our typical preamble about disabling sanity
checks, use a separate event to indicate that sanity checks failed.
This change is intended to work together with the related change to
sanity.bbclass in OE-Core.
Fixes [YOCTO #2336].
