ci/profiles: strip everything after the `-' in utsname.release

This fixes the script under FreeBSD (tested 13.2) FreeBSD 13.2
has `13.2-RELEASE-p3' in its uname(2) utsname.release.  While
the `.2' component is a welcome addition over the old script,
Perl parses the `-' as a subtraction operation, which isn't
what we want.
