util/lint/kconfig_lint: Ignore C preprocessor macros in code

To see which Kconfig symbols are actually used, and to verify that
they're used correctly, kconfig_lint scans the C code. It gives an error
if it sees a CONFIG(symbol) where the symbol doesn't exist.

This creates a problem when a C preprocessor macro is created to match
multiple Kconfig symbols. The simple solution here is to just ignore
those C preprocessor macro definitions as beyond the scope of this
linter.
