Kernel: Panic if the init process dies
If init crashes, all other userspace processes exit too, thus rendering the system unusable. Previously, the kernel would still keep running even without a userland, showing just a black screen without any indication of the issue. We now panic the kernel, which shows a message on the console. In the case of the CI runners, it shuts down the virtual machine, so we don't have to wait for the 1 hour timeout if an issue arises with SystemServer.
