desktop-shell: Fix black edges on scaled desktop pattern

Filter sampling outside the source image can leak black into the edges
of the
desktop image. This is most easily seen by scaling the default tiled image
with this weston.ini:

# no background-image and no background-color
background-type=scale-crop
clients/desktop-shell.c
