Martin Povišer d7fc8fe98f &mfs: Handle blackboxes robustly 
When the network is being handed over to the "sfm" core, all blackboxes
are modeled by inserting new PIs, POs, and those being connected by
buffers to the nodes representing the CIs, COs. Make two changes:

 * Robustly deny the fake PIs from being considered when shopping for
   LUT fanin substitutions. Such reconnection occurring would trip up
   the code reintegrating the result.

 * Make sure the buffer connecting the fake-PO to the CO doesn't get
   rewritten as part of the `mfs` transformation, and extend this
   protection to any whitebox models.
