Revert "Makefile: Fix install error with make -j option"

This reverts commit d2aae847

.

It is completely and utterly broken.  Module install should not build
any files, and adding broken dependencies to "help" it build files is
complete and utter sh*t.

The kernel should not be built by root, and "make install" and "make
module_install" (that for obvious reasons need to be run as root)
absolutely must not build any files.  They should only ever copy the
already-built files over.

So having dependencies for the install targets is wrong, wrong, wrong.

If you try to install a kernel without building it first, you *should*
get errors. The build system shouldn't try to help root build the files.
