kgssapi: Remove broken MOD_UNLOAD code
The module panicked at unload with "recursing but non-recursive rw".
There is a comment that "Unloading of the kgssapi module is not
currently supported" and the MOD_UNLOAD case falls through to returning
EOPNOTSUPP anyway. Just #if 0 the code in the unload path, leaving it
as a hint in case someone implements unload support later on.

vt: Allow VT_SETMODE with frsig=0
Linux does not check that any of the signals in vt_mode VT_SETMODE ioctl
(relsig, acqsig, frsig) are valid, but FreeBSD required that all three
are valid. frsig is unusued in both Linux and FreeBSD, and software
typically leaves it unset. To improve portability, allow frsig to be
set to zero.

diff3: Use logical-not, not bitwise for booleans
And compare impcompat != 0 as it's actually an integer incremented on
each use of one of the AeExX3 options.

diff3: Remove bespoke getopt.h
diff3's getopt.h included a function declaration without a prototype,
which produces a compiler warning. Just remove the bespoke getopt.h
and use the system header.
