t/verify: test cases for running pattern and pattern_hdr

Add test cases for the recently added verify_pattern_interval and
verify=pattern_hdr options to our pre-existing sets of tests.

In some cases verify failures do not produce non-zero return values
unless verify_fatal is set. Add verify_fatal=1 to affected test cases.
