Add a new hook: 92-crashkernel.install 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.

92-crashkernel.install: fix exit code 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.
