Kconfig: Escape variable to accommodate new Kconfig versions
Kconfig 4.17 started using the $(..) syntax for environment variable
expansion while we want to keep expansion to the build system.
Older Kconfig versions (like ours) simply drop the escapes, not
changing the behavior.
While we could let Kconfig expand some of the variables, that only
splits the handling in two places, making debugging harder and
potentially messing with reproducible builds (e.g. when paths end up
in configs), so escape them all.
