As 67d34a6a391369269a2e5dba8a5f42cc4cd50231 said, 'oldnoconfig' doesn't
set new symbols to 'n', but instead sets it to their default values.

So, this patch replace 'oldnoconfig' with 'olddefconfig', stop making
people confused.

PS: the document in conf.c fixed in another mail, "[PATCH] [Signed-off]
kconfig: document oldnoconfig to what it really does in conf.c"

The reason that I didn't make this change myself is that I'm afraid that
things depend on 'oldnoconfig' existing. For example, ktest.pl has it
hardcoded. That may not be the only script that uses it.

I think a better solution would be to make oldnoconfig do just that, set
everything to 'n' as the name implies, and we can create a olddefconfig
to do what it does now.

Yes, but I think very few scripts use it up to now, because it's
"fresh".

Lots of configs can't be set to 'n', they expect digit or other string.

Later we fix it, bigger the problem becomes.
