Filter mirror monitors from the monitors list

For the purposes of window placement or arranging window manager or plugin controls, screens that are just mirrors of other screens should be ignored, so filter them out of the monitors list.

The bug that caused me to file this is that in GNOME Shell if you have mirrored screens, drag-and-drop is all broken in the overview because the workspace drop rectangle for the mirrored secondary monitor is placed on top of the primary monitor. Trying to figure out where we should ignore that secondary monitor, I couldn't think of any reason we need them at all, hence this patch.
