Fix confusion between size_t and ssize_t readfile returns a value of type ssize_t (signed) and returns -1 if an error occurs. In auth_readdb_internal, however, we were assigning the return value of readfile to a variable of type size_t (unsigned), but then testing this unsigned value to see if it was < 0, a contradiction. We would thus simultaneously fail to report the error in readfile and would end up with a corrupted length value.
