netifd dhcp: send DHCP client ID by default

Some ISPs require the client ID to be set in the DHCP and DHCPv6
requests. OpenWrt sets the client id for IPv6 but not for IPv4 by
default.

Align this behavior between DHCPv4 and DHCPv6.

ISPs that require this measure are Deutsche Glasfaser as well as some
Entega connections.
