coredumpctl: show --help text if "coredumpctl help" is called

Browse Source 
Most of our programs that take "verbs" make the "help" verb either
equivalent to passing the --help switch (or at least print a message
redirecting the user to that switch). Do so in coredumpctl too, in order
to minimize surprises.
