Subject: [PATCH] wayland: disable windowless NPAPI plugins

They are seriously broken. We will not enable these in Fedora until the
upstream bug is fixed. The only known plugin this affects is the
gnome-shell browser plugin, which we don't want to support anyway due to
the huge number crash reports.
