libio: Flush-only _IO_str_overflow must not return EOF (bug 28949)
In general, _IO_str_overflow returns the character passed as an argument on success. However, if flush-only operation is requested by passing EOF, returning EOF looks like an error, and the caller cannot tell whether the operation was successful or not. _IO_wstr_overflow had the same bug regarding WEOF.
