cbmem console: make verstage first class citizen
The conditions in cbmem console for supporting verstage
were implicitly utilizing CONFIG_BOOTBLOCK_CONSOLE to handle
the cbmem console enablement. Fix it so verstage is a first
class citizen for deciding actions pertaining to cbmem console.
BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built and booted glados using verstage. cbmem console
shows verstage output.
