egl/wayland: resolve quirky try_damage_buffer() implementation

The implementation was added with commit d085a5dff5b and effectively
provided a hidden dependency.

Namely: the codepath used was determined solely during build time. Thus
if we built again new wayland and then run against older (yet still
within the requirements, as per the configure) one will get undefined
symbols.

As of earlier commit 36b9976e1f9 "egl/wayland: Avoid race conditions
when on non-main thread" the required version was bumped to one which
provides the API, thus we can drop the quirky solution.
