sculpt: restrict un-merging of fb connectors

Browse Source 
In setups with 3 or more displays, allow the un-merging of connectors
only for the last mirrored connector. Otherwise, the operation would
implicitely change the order of connectors because the new discrete
connector needs appear after all merged connectors.
