Update config files (bnc#1161832).
    
    Disable CONFIG_MODULE_SIG on i386. We don't run pesign on i386 builds,
    hence the modules are not signed at all. This results in module
    verification failures and warnings.
    
    CONFIG_SECURITY_LOCKDOWN_LSM depends on (selects) CONFIG_MODULE_SIG, so
    we have to disable it too. But it makes no sense to lockdown without
    module signature anyway.
