Drop the include of <ufs/ffs/ffs_extern.h> from usr.sbin/makefs/ffs/ffs_bswap.c

and usr.sbin/makefs/ffs/ffs_subr.c as they have no need of anything in that
file.  No other programs or libraries include <ufs/ffs/ffs_extern.h> (nor
should they as it is totally in-kernel interfaces). For added protection
I enclosed the entire contents of <ufs/ffs/ffs_extern.h> in ifdef _KERNEL.

Feedback from:	Bruce Evans and Tai-hwa Liang
