Remove debug output when coverage fails (#20733)

* Remove debug output when coverage fails

When coverage fails, it logs megabytes of debug to stdout, which seems
to break the drone ui as well as the log output download in drone,
presumably because of the size. I think with removal of this print, we
should still see any errors created by gocovmerge.go, but a few CI runs
may be necessary to get it to fail again.
