tests/kms_flip: Use fixed size (2kx2k) buffers for dummy load

Make the dummy load independent of the display resolution by using a
two fixed size dummy bos to generate the load. As a final step do
another copy from one of the dummy bos to the fb to make sure there's
a dependency between the dummy load and any subsequent operation on
the fb.
