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.)
