Remove android, dinput, hid, mfi, qnx, x, xinput from the autoconfig directory

[davidhedlund]

The RetroArch Flatpak package supports the following controller drivers via the Settings -> Drivers -> Controller menu:

• linuxraw
• parport
• sdl2
• udev

The directory /app/share/libretro/autoconfig contains sub-directories for various controller configurations, including:

• android
• dinput
• hid
• linuxraw
• mfi
• parport
• qnx
• sdl2
• udev
• x
• xinput

The sub-directories not supported by the Flatpak package settings (android, dinput, hid, mfi, qnx, x, xinput) could potentially be removed if they are not needed for any specific use cases or configurations.

Also, in free systems like flatpak remote-modify --subset=floss flathub which retroarch is downloaded from, it's unusual to encounter data dedicated to proprietary drivers like xinput and dinput.
