Fixed a bug in PCell parameter computation 

"coerce_parameters" and "callback" was called with the client layout
instead of definition layout, hence the DBU was incorrect if both layouts have different DBU.

This became visible on the computed character dimensions of the Basic.TEXT
PCell when the client layout had a DBU != 1nm.
