devel/rubygem-fast_gettext1: Mark broken with Ruby 3.2

This port was created before Ruby 2.7 was available.  Ruby 2.7
deprecated $SAFE / Object#{taint,untaint,trust,untrust}, and those where
removed in Ruby 3.2.  fast_gettext 2.1 removed suppord for these
deprecaded features, but for the 1.x version, we should just mark the
port broken for Ruby 3.2 because such code will not run.

Not bumping portrevision because the default is still to use Ruby 3.1.
