Now that the product and board config pass makefiles
to mk2rbc, we don't need to support passing a product
name.

The current behavior of mk2rbc is that it can accept either
a makefile to convert, or if it's also generating a launcher,
it must accept a product name instead of a makefile.
For board configuration, we need to convert a specific makefile,
but we also want to generate a launcher. Change mk2rbc so that
its non-flag arguments can be either makefiles or product names.

Generate version settings from build/make/core/version_defaults.mk.
The generated settings are then loaded into the launcher code and passed
to the environment setup code.
