I didn't find any use of this macro in the current kernel tree (with git
grep). KTHREAD_SIZE is no longer used for a very very long time. So
let's remove this definition.

Even more, CONFIG_SMALL_TASKS has gone and only page size we support is 4K.
It looks like that similar patch has been submitted several times by different
people but never got merged, so if it helps:
