docs: document panic fully in sysctl/kernel.rst

The description of panic doesn’t cover all the supported scenarios;
this patch fixes that, describing the three possibilities (no reboot,
immediate reboot, reboot after a delay).

Based on the implementation in kernel/panic.c.

panic
=====
The value in this file represents the number of seconds the kernel
waits before rebooting on a panic. When you use the software watchdog,
the recommended setting is 60.
The value in this file determines the behaviour of the kernel on a
panic:
* if zero, the kernel will loop forever;
* if negative, the kernel will reboot immediately;
* if positive, the kernel will reboot after the corresponding number
of seconds.
When you use the software watchdog, the recommended setting is 60.
