stdio-common: Remove _IO_vfwscanf

Browse Source 
The symbol has never been exported, so no compatibility symbol is
needed.  Removing this file prevents ld from creation an exported
symbol in case GLIBC_2_0 expands to a symbol version which
does not have a local: *; directive in the symbol version map file.
