perf: fix perl binding support

The build of the perl integration has been broken for some time.

Update the PERL_* variables so that it can find libperl in the new
location.

This then fails because the Perl headers cause warnings and the feature
checks run with -Werror, so disable the errors.

The perf-dbg package then has target build paths, so set INSANE_SKIP for
now until this is resolved.
