Upgrade to GLFW 3.4

GLFW 3.4 is out. As soon as go-glfw is ready, we should upgrade the dependency as it will bring a better support of Wayland.

no this makes it impossible for us on LTS to build this.
Some of us like our OS not to crash and bug out.

I am already having to build go from source.

Also the binaries don't work for me at all. they just fail silently.

wait nvm now they are working very odd.

ignore me.
