zephyr: override the sysworkq stack size for npcx
This lowers the stack size for the sysworkq task to bring it close to
the 75% target watermark.
This is the Zephyr workqueue thread, it is used by the k_work_submit()
API and started showing up after 783543b32:
uart:~$ kernel stacks
...
0x200c7ed0 sysworkq (real size 288): unused 80 usage 208 / 288 (72 %)
BUG=b:183748844
