tools lib traceevent: Refactor pevent_filter_match() to get rid of die()
The test_filter() function is for testing given filter is matched to a
given record. However it doesn't handle error cases properly so add a
new argument err to save error info during the test and also pass it to
internal test functions.
The return value of pevent_filter_match() also converted to pevent_errno
to indicate an exact error case.
