[PATCH 09/12] dwarf_loader: Add cu parameter to tag__set_spec() and dwarf_tag__set_attr_type()

[Arnaldo Carvalho de Melo <acme@kernel.org>]

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

Thread the cu parameter through the reference-setting helpers, in
preparation for using it to track which offset space (main file vs dwz
alternate file) each reference targets.

The cu parameter is currently unused: dwarf_tag__set_attr_type() silently
ignores the extra macro argument, and tag__set_spec() marks it
__maybe_unused.

No functional change.
