Dismiss warnings about window position being unavailable on Wayland.

In addition to the other glfw patches, this one is required on certain
compositors such as niri and waywall to be able to launch Minecraft at
all.

This patch expands the suppression to setting positions. This
prevents Minecraft Forge environments from crashing on Wayland when
strict error callbacks are used.

Original get-position fix by: uku <hi@uku.moe>
Expanded to include set-position, inspired by Prior5151's fix on AUR.
