libdw: Simplify __libdw_visit_scopes' tag checks
The former classify_die() was splitting tags into more classes than
actually needed.
The one place that used the "imported" die_class now just compares to
DW_TAG_imported_unit directly.
The recursion check was squashing "match", "match_inline", and "walk"
into the same action. Now that uses the new may_have_scopes(), which
just returns true for all tags that had those classifications.
The net result has no functional change, but performs better.
