weston-egl-ext: Define EGL tokens harder for old Mesa

Older versions of Mesa provided header definitions for the
EGL_WL_bind_wayland_display extension, but an earlier version of the
extension which only provided the (un)bind entrypoints, and not
QueryWaylandBuffer. Detect this half-provision and make sure we export
the QueryWaylandBuffer definitions as well.

Fixes build failure with EGL on Ubuntu 12.04.
