[PATCH 3/6] dhcrelay: Use network byte order for the interface id value

[Bjørn Mork]

The byte order does not matter for relay operation, but keeping
integer values in network byte order makes the output consistent
independent of the relay endianness.  I.e. configuring an
interface id of 1234 will always give the same system independent
option value.

This makes debugging easier.
