[BusyBox] ash Intro banner (others too?)

[David Douthitt]

When I start busybox ash, I get the intro banner.  This would normally
be fine, except it interferes with the informational output I have set
up for users of my distribution.  Thus I propose:

...for me, I'd just as soon as #undef INTRO_BANNER, but I think that it
is better to leave it enabled (at least initially) for most people...
