Fix Retropie options that are not supported under Arch Linux/Arch Linux Arm

[V0rt3x667]

Retropie has some very specific customizations that are either unique to Debian/RaspberryPI OS based systems or rely on custom builds of the SDL & SDL2 libraries.

• [x] Remove legacy options related to the proprietary Broadcom drivers for the Raspberry Pi 2,3 & 4
• [ ] Remove SDL hints only available in Retropie's SDL builds: SDL_HINT_VIDEO_RPI_SCALE_MODE SDL_HINT_VIDEO_RPI_RATIO SDL_HINT_JOYSTICK_COMPAT_NAME
• [ ] Remove options relating to OMX
• [x] Look into the start-stop-daemon as this causes a crash when launching setup scripts from within EmulationStation
• [ ] Retropie installs x11 & Matchbox window manger for apps that do not run under KMS/DRM. Only a very old version of Matchbox is available in the AUR. Look into using Wayland (Sway or Cage) & xorg-wayland
• [ ] Remove legacy options from runcommand.sh eg tvservice
