Various updates (#271)

* Update kwin_wayland

* Update plasmashell

* Update pacman-hook-fontconfig

* Update ksplashqml

`/usr/share/qt/translations/*.qm r,` is also in the qt5 abstraction. However, it seems that all other rules therein are not needed so I didn't use that abstraction.

* Update startplasma
