syz-manager: add corpus triage mode

Add corpus triage mode and support it in testbed.
This is useful to benchmark just the triage phase
w/o any subsequent fuzzing. First, fuzzing is more random.
Second, if triage duration is different in different versions,
then they will do different amount of fuzzing in fixed testbed time.
