monitor: Don't only use 'winsys ID' to check sameness

Browse source 
What determines whether one MetaMonitor is the same as the other should
be whether the actual monitor is the same. The way to check this is
comparing the EDID vendor/product/serial fields. Whene these are
incomplete, fall back on the 'winsys ID'.
