bde 2652de9da3 Don't default to (wrong) SCO definitions for _IOR() etc. if <sys/ioctl.h>
doesn't happen to be included before this header.

This header was missed in previous cleanups because it didn't include
<sys/ioctl.h> or <sys/ioccom.h>.  Clean it now:
- #include <sys/types.h> since it is necessary to make the header self-
  sufficient (there are a couple of u_char's).
- uniformized idempotency ifdef.  Copied the style in the 4.4Lite
  ioctl headers.
