[PATCH weston v2 2/6] noop-renderer: Set the buffer size on attach requests

[Emilio Pozuelo Monfort]

From: Emilio Pozuelo Monfort <emilio.pozuelo at collabora.co.uk>

This lets the compositor know the size of the surface as calculated
in weston_surface_set_size_from_buffer(), and fixes a couple of
tests when using the headless backend.
