[PATCH v2] Remove silentoldconfig from "make help"; fix kconfig/conf's help

[Marc Herbert <marc.herbert@intel.com>]

As explained by Michal Marek at https://lkml.org/lkml/2011/8/31/189
silentoldconfig has become a misnomer. It has become an internal interface
so remove it from "make help" to stop confusing people trying to use it as
seen for instance at https://chromium-review.googlesource.com/835632

On the other hand, correct and expand its description in the help of
scripts/kconfig/conf.c
