[PATCH 2/4] kconfig: make conf -s (silent) a modifier rather than an input mode

[Andres Salomon <dilinger@xxxxxxxxxx>]

Rather than 'silentoldconfig' being its own input mode, just make it
the same as 'oldconfig' but with a modifier.  This is just a 'silent_mode'
toggle that allows us to add future silent targets.

So, 'silentoldconfig' calls 'conf -s -o' rather than 'conf -s'.
