perf/scripts: Remove check-perf-trace from listed scripts

The check-perf-trace script only checks Perl functionality, and
doesn't really need to be listed as as user script anyway.

This only removes the '-report' shell script, so although it doesn't
appear in the listing, the '-record' shell script and the check perf
trace perl script itself is still available and can still be run
manually as such:

$ libexec/perf-core/scripts/perl/bin/check-perf-trace-record
$ perf trace -s libexec/perf-core/scripts/perl/check-perf-trace.pl
