Fix nagging make_dev() warnings

[Frank W. Josellis]

Currently I'm receiving the following warning whenever moused is invoked:

Starting moused:
WARNING: driver sc should register devices with make_dev() (dev_t = "#sc/255")

Actually nothing appears to be wrong with the sysmouse, so this is quite 
annoying and I've tried to get rid of these messages. Please consider the 
two patches below for fixing this issue.

Note that spec_vnops.c.patch just reimplements a feature of the FreeBSD 
4.x kernel (which in my opinion doesn't hurt). This prevents repetitions 
of the above warning, but it occurs once at the initial start of moused. 
The second patch corrects this (though it's not clear to me why it occurs 
at all).
