Modified Plasma launch script to (crudely and unreliably) detect if it has to run on the framebuffer or not
* Re-add powerdevil and polkit-kde-agent as runtime deps to postmarketos-ui-plasma-mobile * Add kwinrc to start applications maximized
* Add postmarketos-ui-plasma-mobile * Add more required packages * Upgrade plasma sources * Modernize APKBUILDs * Make it run in general * Support RGB32 framebuffer with BGR order (thanks @zhuowei!)
