db v4: add column last_lu_seen_ps

Location Updating procedures from both CS and PS overwrite the same
last_lu_seen field of a subscriber. For upcoming D-GSM it will be important to
distinguish those, because only CS attaches qualify for MSISDN lookup.

Add column last_lu_seen_ps, and upon PS LU, do not overwrite last_lu_seen, so
that last_lu_seen now only reflects CS LU.

In the VTY, dump both LU dates distinctively.
