Moved common function in kms_color and kms_color_chamelium to kms_color_helper.c

kms_color and kms_color_chamelium shared common functions.
Moved them to tests/kms_color_helper.c to avoid code duplication.

(v4)
        Made a library kms_color_helper.c which is specific to
        kms_color and kms_color_chamelium.
