libio: Remove codecvt vtable [BZ #24588]
The codecvt vtable is not a real vtable because it also contains the
conversion state data. Furthermore, wide stream support was added to
GCC 3.0, after a C++ ABI bump, so there is no compatibility
requirement with libstdc++.
This change removes several unmangled function pointers which could
be used with a corrupted FILE object to redirect execution. (libio
vtable verification did not cover the codecvt vtable.)
