[Bug]: firefox not working under wayland

[TobiaszCudnik]

Problem description

Because wayland seems to be deliberately disable in GTK3 (and 4), Firefox doesnt start, crashing on "no DISPLAY" instead.

Considering its 2023 and both wlroots and sway are available in this repo, theres no reason to disable wayland in one of the main UI libraries.

-Dwayland_backend=false in https://github.com/termux/termux-packages/blob/master/x11-packages/gtk3/build.sh

What steps will reproduce the bug?

1. Start sway
2. Start wayvnc
3. Start xterm
4. Start firefox

What is the expected behavior?

Firefox starts using the wayland renderer.

theres no reason to disable wayland in one of the main UI libraries.

Actually there is a reason. In the most cases Wayland compositors require real GL which is not available on Android devices.
