networkd-config: force ipv4 clientid to 'mac'

Traditionally the DHCP clients will send the ethernet
MAC address as the 'ClientID' in the DHCP request.

DHCP on IPv6 introduced a new identifier called a DUID
as the primary system identifier that is sent to the DHCP
server.  This was also added back to IPv4 via RFC 4361
and is the default in systemd-networkd.

Some legacy system installations do not support DUIDs
and as a short-term fix, we will force 'mac' to be used
instead of 'duid'.  See openbmc/openbmc#1280 for long-term
discussion.

Fixes openbmc/openbmc#1272.
