pkg/report: improve corrupted report detection
1. If we see should_failslab frames during report parsing,
that's a corrupted report with intermixed frames from
fault injection stack.
2. If we matched report title and this report should contains
a guilty stack frame, but we failed to extract any frame,
consider it as corrupted.
New tests added. Also one of the old tests is fixed.
