[PATCH wayland 2/6] wayland-egl: make wayland-egl-backend.h C++ safe

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

private is a reserved keyworkd in C++. Thus to make things work, we
should use something else - wl_egl_window::driver_private.

Make sure to do so only for C++ contexts, or otherwise it will break the
API - leading to build failures when used alongside existing Mesa.
