[PATCH] Add argument-less ppdev ioctls to compat_ioctl.h

ppdev's ioctls are not available for 32bit apps on 64bit systems.  There
are four ioctls which take no argument at all (so they are compatible
between 32bit and 64bit), these numbers do not clash with any other ioctl
code, and so I see no reason why not applying patch below.

It solves problem VMware users are faced on 64bit systems if they want to
use direct access to the parallel port.
