ext/coverage/lib/coverage.rb (Coverage.line_stub): use only line events

Browse source 
It wrongly used all linenos of ISeq#trace_points which includes not only
line events but also call, return, and other events.  So, the result
included some linenos that can not be covered at all by line coverage.
