Avoid creating (and subsequently using) fake opt_*.h files
when the modules are built with the kernel and hence actual
opt_*.h files are available in ${KERNBUILDDIR}. Fix a few
small bugs that would prevent this from working.
At last the build options of the modules become consistent
with those of the kernel unless the MODULES_WITH_WORLD way
still is used.

regocnized as such at the time. Now that the other bogons in the
tree have been fixed, we can remove this ugly kludge.
o Remove stale/bogus opt_foo.h files. These are left over from
by-gone resources. And they point to the need, yet again, to
improve the build system so meta information is only in one place.

This means that the kernel can be totally self contained now and is not
dependent on the last buildworld to update /usr/share/mk. This might
also make it easier to build 5.x kernels on 4.0 boxes etc, assuming
gensetdefs and config(8) are updated.
needed for ages, but keeps getting cut/pasted into new Makefiles.
(Once apon a time it was used to activate mount arguments in
<sys/mount.h>, but that was killed with extreme prejudice long ago)
