phosh/plamo/sxmo: _pmb_recommends: add font-noto
Let all UIs which depend on mobile-config-firefox depend on font-noto to fix #1071 (closed).
This is added to _pmb_recommends, so users can decide to install other fonts and uninstall this one.
Phosh and Plasma Mobile already depended on font-noto-emoji, let Sxmo depend on it too for consistency.
