[qfcc] Update offset for aliased defs

Browse source 
When getting an offset alias of an already aliased def, the offset needs
to be updated so it points to the correct part of the def. This is
actually a rather old bug but it got uncovered somehow with my rework of
the ruamoko semantic processing (probably an altered cast).
