kdumpctl: Use kexec file based mode to unload kdump kernel

Browse Source 
Currently old kexec syscall denies unloading a kernel if secureboot is enabled.
I think this is not right behavior and should be changed. But for now, use
new syscall if secureboot is enabled and that allows unloading kernel.
