ecore-wayland: test for subsurface protocol in wayland core

The subsurface protocol was moved into Wayland Core
around v1.3.90 (i.e. v1.4.0).

Test if subsurface protocol is part of wayland-client.h.
If not, we include our own copy of the protocol header.

Also, some whitespace cleanup in ecore_wl.c.

Tested with Wayland 1.3.0 and 1.3.90 (master:360dca5).

Fixes T529
