Subject: ci/profiles: rewrite in Perl

Reading os-release(5) is a bit more painful, now; and still
requires using the shell.  However, sharing code between *BSDs
and being able to use v-strings for version comparisons is much
easier.

Test profiles for *BSDs are also trimmed down and more focused
on portability stuff.
