kconfig: Have streamline_config process menuconfigs too

Some menuconfigs in the Kconfig files have prompts and dependencies.
Currently, streamline_config misses these, and this can cause
streamline_config to keep modules enabled that should not be, and
even worse, not enable those that should.

This patch makes streamline_config process menuconfigs just like it
would process a config.
