Remove nvram clear/list/dump, deprecate nvram vboot

We've cleared up all references in Chrome OS to nvram clear, list, and
dump. The remaining usage of the nvram command is by crossystem for
vboot parameters, which is in the process of being migrated to
crossystem (crbug.com/1032351, crbug.com/1030473). Make the help
message clear we don't want anyone else to start using it in the mean
time.
