Fixes internal pin parsing error in ASAP7 liberty file. 

This fix addresses an issue I saw with the ASAP7 liberty files and
ABC. ASAP7 lists internal pins in its liberty file which ABC's liberty
parser doesn't account for. This causes an assert to be triggered. This
fix simply adds interal pins to the ignore list.
