This patch adds a few missing ioctls which were required by Wine.
SIOCGIFNETMASK, SIOCGIFBRDADDR and SIOCGIFMTU are fully implemented,
while SIOCGIFFLAGS and SIOCGIFCONF are stubs.
Added a dummy TIOCSTI ioctl placeholder. This is a dangerous ioctl that
can be used to inject input into a tty. Added for compatibility. Always
fails with EIO.
