freedreno/rnn: also look for .xml.gz
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.
