[PATCH 5/5] init/Kconfig.expert: Factor out "if EXPERT" conditions using showif

[Josh Triplett <josh@joshtriplett.org>]

Use the new showif construct to simplify the expert menu.  Now, making a
symbol no longer invisible when !EXPERT requires moving it out of the
EXPERT menu, which makes it more difficult to break the EXPERT menu.
