x11: fix ICC profiling for multiple monitors 

To find the correct ICC profile X atom, the screen number was calculated
directly from the xrandr order of the screens.
But if a primary screen is set, it should be the first Xinerama screen,
even if it is not the first xrandr screen.

Calculate the the proper atom id for each screen.
