opencomposite-helper: drop

This helper script made use of `VR_OVERRIDE` which causes issues with
some applications/games. As detailed in 3rd-party documentation[0] the
recommended way to setup OpenComposite is to configure
`$XDG_CONFIG_HOME/openvr/openvrpaths.vrpath` instead. This is also
documented on the NixOS Wiki[1].
