Some EDID-provided chromaticity coordinates for the blue colour are
too far from the expected ones, causing blue to be rendered as purple
(or cyan, in some cases). This is due to broken primaries, as all the
standard colorspaces' blues are clustered nearby.

This CL adds a sanity check for the blue coordinates (need to be to
the left and below of a given point) and adds a unit test for it. If
the condition doesn't verify, we just ignore this ColorSpace -- which
means we'll treat the monitor as sRGB.
