[i-g-t] tests/kms_colorop: Use local variable for color pipeline cap

[Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com>]

Following the pattern in kms_color_pipeline, set
DRM_CLIENT_CAP_PLANE_COLOR_PIPELINE once and stash the result in a
local variable, then propagate it to display->has_plane_color_pipeline
after the final igt_display_require() (which reinitializes the display
state). This avoids calling drmSetClientCap() twice.
