[skip ci]: too many packages changed, build won't finish in time.
ollieparanoid made sure that this builds for x86_64,
aarch64, armhf, armv7. Also he tested that this boots up
in qemu-amd64.
This MR updates the app to the latest commit (currently from 2 days
ago). It also updates plasma-angelfish, but I changed the $pkgrel to
follow the format of the other Git packages.
This also re-enables plasma-angelfish and vvave in the default Plasma
Mobile installation, as they were previously disabled due to
qt5-qtwebengine (which they depend on) requiring a soname bump
upstream.
