generateBuildIDs: Fix error handling.
commit e6bdf7 made it so that we don't give a warning or error message
for non-kernel ET_REL object files with missing or bad build-ids. But
we still (unintentionally) failed generateBuildIDs which made us skip
generating the cpioList causing an obscure failure message.
Move the sanity check earlier so we don't process such object files at
all. And if there is any real error from generateBuildIDs give a clear
error message and explicitly set processingFailed.
