kernel: Stack pointer random depends on MULTITHREADING

Browse source 
Don't pretend with have stack randomization without multithreading.
When multithreading is disabled the "main" thread never starts. Zephyr
will run on the stack used for the z_cstart(), which on most
architectures is the interrupt stack.
