arch: increase priv stack with built-in stack-overflow checking

Browse source 
This commit increases the privilege stack size to 512 bytes,
when building with support for built-in stack-overflow checking.
This is in alignment with #10729, which increases the privilege
stack size when MPU-based stack guarding is enabled.
