Dolphin fails to launch game on Wayland [Upstream Dolphin]

[Noodlez1232]

Upstream dolphin doesn't support Wayland, but will still run its first GUI under Wayland (since QT supports Wayland), so it needs to be launched with the environment variable QT_QPA_PLATFORM=xcb to force it to run under X11.

This is only a problem with systems that have their QT_QPA_PLATFORM env variable set to anything else (Usually set to wayland;xcb to force Wayland usage, since X11 is default for QT).
