interfaces: T3871: keep the address policy the distribution ships

Only the first matching link file is applied, and ours sets just the name,
so the address policy shipped with the system never ran on any interface.
Hardware with a permanent address was unaffected - there was nothing to
apply - but a modem, which has none, was left on whatever random address its
driver had picked that boot, a different one every time.

Spell the policy out again. A permanent address is still kept where there is
one, and a device without one is given an address derived from the machine
and the device, which is the same on every boot of that machine. An address
set through the CLI is applied later and is unaffected.
