config: enable some useful features on !SMALL_FLASH devices

enable kernel features needed for procd-ujail, procd-seccomp, lxc and
more on devices with big enough flash. Those packages are currently
useless in binary builds due to missing kernel features.
Enable the features on devices which can bare with the extra space
consumption.
