[PATCH 04/12] dwarf_loader: Introduce dwarf_cus__process_cu()

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Finishing the separation of creating a dcu/cu pair from processing it,
as we'll need to add the new dcu/cu pair to the list under cus__lock(),
so that we process it in order to keep a reproducible BTF encoding.
