Subject: add some lines to delete unused TracePoint

`TracePoint.stat` returns the "to be deleted" TP numbers, and
http://rubyci.s3.amazonaws.com/graviton2/ruby-master/log/20210810T030003Z.fail.html.gz
shows there is a "to be deleted" TP.

This patch uses only :line event and add some lines to allow MRI
deletes "to be deleted" TPs.
