Subject: [PATCH v2 1/6] kbuild: align W=e with CONFIG_WERROR

CONFIG_WERROR sets KBUILD_CPPFLAGS while W=e would only set KBUILD_CFLAGS.

As a preparation to unify the two mechanism, align their effects.

While at it, add some alignment whitespace to prepare for later additions
to the list of changed variables.
