libstdc++: Remove redundant explicit instantiations
These function templates are explicitly specialized for char and wchar_t streambufs, so the explicit instantiations do nothing. Remove them, to avoid confusion. libstdc++-v3/ChangeLog: * include/bits/streambuf.tcc (__copy_streambufs_eof): Remove explicit instantiation declarations. * src/c++11/streambuf-inst.cc (__copy_streambufs_eof): Remove explicit instantiation definitions.
