pkg/report: detect executor failures
Currently all executor fail errors go into "lost connection" bucket.
This is not very useful. First, there are different executor failures.
Second, it's not possible to understand what failures happen how frequently.
Third, there are not authentic lost connection.
Create separate SYZFAIL: bugs for them.
Update #573
Update #502
Update #318
