dhclient: T3940: Added lease file argument to the `dhclient -x` call
When `dhclient` with the `-x` option is used to stop running DHCP client with a lease file that is not the same as in the new `dhclient` process, it requires a `-lf` argument with a path to the old lease file to find information about old/active leases and process them according to instructions and config. This commit adds the option to the `02-vyos-stopdhclient` hook, which allows to properly process `dhclient` instances started in different ways.
