WIP: Plasma Mobile screen rotation

This just updates some packages to newer commits from git, to get rotation in Plasma Mobile working. I also installed iio-sensor-proxy - I think that's required?

I doubt that we want to have this merged, so this is mostly as a reference if someone wants to try as well. (I needed this so I can develop https://phabricator.kde.org/T12903 🙂 )

An idea of mine is to have a KDE nightly repository which automatically builds packages from git master so they can be 1. tested and 2. development for upstream can be done on postmarketOS. Automatically building ~100 (?) packages daily on CI could be a bit wasteful though. Maybe we can have a git repo with APKBUIlDs which get automatically converted from stable APKBUILDs (1. add _git to pkgver, 2. add line _commit="something", 3. set/modify builddir variable, 4. modify source line to pull $_commit from git and not from stable download.kde.org, 5. run pmbootstrap aportupgrade $package, 6. run pmbootstrap checksum $package -- shouldn't be hard to automate all in all) and maintained on a best-effort basis (meaning it might be necessary to remove broken patches from the APKBUILD or something). I'm not sure that we actually really need that but it definitely would be nice.
