util/abuild: Ensure that non-Chrome OS builds are non-Chrome OS

Sometimes boards enable it by default, making the Kconfig option
impossible to disable without messing with the Kconfig files. This
shouldn't happen, so report on such occurrences early.

TEST=Tried building GOOGLE_KOHAKU through abuild with -x, without
-x and both cases after having added a "select CHROMEOS" for testing
and it failed in the "without -x with select" scenario while properly
configuring and passing all other builds.
