Add an additional environment variable, defaulting to disabled,
that enables the CONFIG_EXPERT configuration option. The purpose
of the CONFIG_EXPERT configuration option is to make non-standard
Kconfig options visible during the configuration process. The
CONFIG_EXPERT option is not, itself, visible during the Kconfig
configuration process, so typical users will never see it nor
any of the non-standard configuration options.
