Subject: [PATCH] [wayland] Reset QT_QPA_PLATFORM to wayland after starting
 Application

We only need to force QT_QPA_PLATFORM to be our own plugin when starting
the application. As KWin starts other processes (e.g. kcmshell5) we need
to ensure that the env variable has a sane value. No other process can
load our QPA plugin after all.
