Rename VB_SOURCE to VBOOT_SOURCE for increased clarity

This renames the VB_SOURCE variable to VBOOT_SOURCE in the build system,
providing increased clarity about what it represents.

Since the submodule itself is called "vboot", it makes sense to use that
name in full instead of a very shortened (and confusing) version of it.
