[PATCH i-g-t 5/5] tests/kms_content_protection: Set screen red/green based on CP Status

[Suraj Kandpal]

Set fb as red when HDCP is disabled and green when HDCP is enabled
rather than randomly setting the color. This helps to visually
verify HDCP's enablement status rather than having to look at the
logs.
