The return value of set_ck_kernel or set_grub_ck is wrongly being used
as the exit code. This hook should exit with 0 or it may result in
unexpected behavior of kernel-install.

At least, this is a plausible suspect for #1993505 - thanks to
@kevin for identifying it - and fixing it should be safe and
correct, so we may as well do it and see if it helps.
To track and manage kernel's crashkernel usage by kernel version,
each kernel package will include a crashkernel.default containing the
default `crashkernel=` value of that kernel. So we can use a hook to
update the kernel cmdline of new installed kernel accordingly.
Put it after all other grub boot loader setup hooks, so it can simply
call grubby to modify the kernel cmdline.
