    c++: Seed namespaces for bindings [PR106363]

    Currently the first depset for an EK_BINDING is not seeded. This breaks
    the attached testcase as then the namespace is not considered referenced
    yet during streaming, but we've already finished importing.

    There doesn't seem to be any particular reason I could find for skipping
    the first depset for bindings, and removing the condition doesn't appear
    to cause any test failures, so this patch removes that check.

            PR c++/106363

    gcc/cp/ChangeLog:

            * module.cc (module_state::write_cluster): Don't skip first
            depset for bindings.

    gcc/testsuite/ChangeLog:

            * g++.dg/modules/pr106363_a.C: New test.
            * g++.dg/modules/pr106363_b.C: New test.
