[Pkg-puppet-devel] Bug#973248: Deprecation warning in Ruby 2.7: $SAFE will become a normal global variable in Ruby 3.0

[Miquel van Smoorenburg]

Package: puppet
Version: 5.5.22-1

This is a similar but different bug as 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=955532 .

I get this warning on a puppet run:

/usr/lib/ruby/vendor_ruby/puppet/file_system/uniquefile.rb:126: warning: 
$SAFE will become a normal global variable in Ruby 3.0

I tried fixing it by setting Warning[:deprecated] = false, but that does 
not work for this specific warning, weirdly enough.

So I tried another minimal approach. This fixes it for me, and it should 
also fix those other deprecation warnings from #955532, so that patch 
can be dropped if you want.
