dhcp: don't re-read DHCP client ID from configuration file for dhclient

Why would we do this? The configuration file we are reading back was
written by NetworkManager in the first place.

Maybe when assuming a connection after restart, this information could
be interesting. It however is not actually relevant.

Note how nm_dhcp_client_get_client_id() has only very few callers.

  - nm_device_spawn_iface_helper() in 'nm-device.c'. In this case,
    we either should use the client-id which we used when starting
    DHCP, or none at all.

  - ip4_start() in 'nm-dhcp-dhclient.c', but this is before starting
    DHCP client and before it was re-read from configuration file.

  - in "src/dhcp/nm-dhcp-systemd.c", but this has no effect for
    the dhclient plugin.
