[PATCH i-g-t] tests/intel/kms_dirtyfb: Use a smaller fb on simulation

[Pranay Samala <pranay.samala@intel.com>]

The test creates, fills and copies full-screen fbs with
the GPU, which is too slow on simulation, and test hits
timeout.

When running in simulation, limit the fbs to 1024x768.
The CRC still covers the whole pipe, and the reference
and test frames have the same layout.
