waylandsink: consider buffer size when copying to wl shm pool

Browse source 
When the sink receives a buffer that is neither a wl_shm one nor a
dmabuf one, this buffer is copied to an internal wl_shm buffer before
being sent to the display.
In that case, the actual size of the received buffer (which may differ
from the one negotiated in the caps) must be used.
