mknod(2): Allow for the creation of fifos with mknod() to satisfy POSIX.
Calling mknod() and mknodat() with S_IFIFO shall be equivalent to
calling mkfifo() and mkfifoat().
Note that we ignore 'dev' if S_IFIFO is passed, like Linux does, but
different from what {Free,Net,Open}BSD do, which require it to be 0.
It's true that the standard leaves anything but 0 undefined for this
case but also note the standard's example which does indeed pass a
'dev' arg and doesn't take any precautions of initializing it:

I don't think it makes any difference in practice, though.
