file: Update for breaking changes in insomniacslk/dhcp

https://github.com/insomniacslk/dhcp/pull/347 changed struct
OptIAAddress to use time.Duration for lifetimes. This is a breaking
change and users need to update.

Note that it still compiles without the changes as time.Duration is an
int64, but the values become incorrect (3600 ns rounded as 0s, instead of 3600s)
