build(7): Document KERNBUILDDIR
KERNBUILDDIR is used by kmod.mk to find the opt_*.h when matching a
kernel to the module. Usually one doesn't need this nob (since most
modules are option invariant or default to the default options everyone
uses), but there are times this generalization doesn't hold.
