Remove device specific overrides / click package bash scripts

• Flatpak overrides in var for halium/libhybris device - As PlaMo no longer supports these devices this can be removed?

• usr/bin contains click package management scripts - these should likely be removed and handled by the OS

• usr/share/alsa contains hardware specific hacks, shouldn't these be handled on the OS side as well?

• etc/gst-droid (halium no longer needed)

• etc/xdg/gstomx.conf (halium)

• etc/profile.d/path.sh (OS hack)

• etc/profile.d/qpa_plugin_wayland.sh (now done by kwinwrapper?)

• etc/init (halium (android) related?)

• etc/NetworkManager/conf.d/53-ignore-rmnet.conf (fairly sure this is halium as well)
