[PATCH 3/4] kconfig: fix backport syntax to work with linux-next next-20220204

kconfig on next-20220204 has a few changes. First the options
stuff has been deprecated leaving only the modules option. For
variables though we can just use shell. And if we use variables
on source we just need to use parens like $(FOO).

Fix all this.

This was tested with a backport generated for v5.15.8.
