    c++: Only emit exported GMF usings [PR114600]

    A typo in r14-6978 made us emit too many things. This ensures that we
    don't emit using-declarations from the GMF that we don't need to.

            PR c++/114600

    gcc/cp/ChangeLog:

            * module.cc (depset::hash::add_binding_entity): Require both
            WMB_Using and WMB_Export for GMF entities.

    gcc/testsuite/ChangeLog:

            * g++.dg/modules/using-14.C: New test.
