Use only one color to run test kms_pipe_crc_basic

I took a step backwards and removed the second color from the test. I can't
recall what was the reason why second color was added to the test. Maybe
someone remembers why this second color was needed? 

I tested with the following sequence that seems to work for me
- unplug VGA
- unplug DP
- unplug DVI
- plug VGA back
- plug DP back
- plug DVI back

run 'kms_pipe_crc_basic --r read-crc-pipe-A-frame-sequence --debug'

The output of the test was the following
