dwarflint: check_dups_abstract_origin, be specific about GNU_call_site dups.

A call site entry has a DW_AT_low_pc attribute which is the return
address after the call and a DW_AT_abstract_origin that is a
pointer to the reference it calls directly or indirectly. So
both may be available also at the abstract_origin (with different
values).
