freedreno/rnn: also look for .xml.gz

Browse source 
libxml2 can load gzip compressed files, so lets look for these too.
This will be useful for installing the register database so that an
installed cffdump/crashdec can use them.  But it isn't too useful
to be able to edit the installed register database, so we can gzip
them to use less disk space.
