perf tools: Improve libperl detection message

Before:

  Missing perl devel files. Disabling perl scripting support, consider installing perl-ExtUtils-Embed

After:

  Missing perl devel files. Disabling perl scripting support, please install perl-ExtUtils-Embed/libperl-dev

Change the message to the standard 'please install' language and
adds Debian-ish package suggestion.
