EMDCHotkey Can't detect keyd when isntalled as a flatpak.

[LiamtheLion879]

When running EDMC as a Flatpak on Linux(Bazzite), EDMC hotkeys can't detect keyd from within the flatpak sandbox. I haven't tested this with installing it outside of a flatpak, but I did go through several hours of troubleshooting doing the following:

• Updated permissions of Flatpak via Flat seal
• Tried in X11 and Wayland
• gave access to all directories in file system as well as specific ones for the keyd and EDMCHotkeys.
• updated the validation script to use flatpak-spawn -host systemctl instead of just systemctl so it could reach outside the container.

I've not had a chance to make this work with flatpak on any version of linux. This plugin does some low level keystroke intercepts which will make it hard to get it working with Flatpak, which is really good at sandboxing.
