Subject: [PATCH] wlx-overlay-s: make openvr support optional, disable on
 aarch64-linux

wlx-overlay-s uses
https://github.com/galister/ovr_overlay_oyasumi/pull/2, which pulls in a
version of ovr_overlay_sys with a build.rs file that doesn't build on
aarch64-linux.

https://github.com/galister/ovr_overlay_oyasumi is a fork of
https://github.com/Raphiiko/ovr_overlay_oyasumi, which is a fork of
https://github.com/TheButlah/ovr_overlay, with the latter not updated in
two years.

Luckily openvr is kinda discouraged, and openxr is the new kid on the
block, and openvr support can be feature-flagged out.

So let's do this, by adding a withOpenVr option to the derivation, that
defaults to false on aarch64-linux, unbreaking it there.

We still keep openvr support for x86_64-linux enabled, to not regress
experience for people already using openvr on x86_64-linux.
