* io.c (ioctl_narg_len): don't use _IOC_SIZE macro on Linux.
On Linux some constants for ioctl(2) doesn't include the size of
its return value and 16bit value; for example FIONREAD 0x541B.
Moreover the manual, ioctl_list(2), says "Note that the size
bits are very unreliable: in lots of cases they are wrong,
either because of buggy macros using sizeof(sizeof(struct)),
or because of legacy values."
So we shouldn't use it.
