community/network-manager-applet: fix after nm upgrade

Currently, it can't be installed (missing so:libnm-glib.so.4).

I've tried to bump the pkgrel only, but it won't build anymore because
the legacy libnm has been removed in the NetworkManager release we're
using (NetworkManager/NetworkManager#308).

Add --without-libnm-gtk to fix it.
