IP address detection incorrectly chooses link local addresses (169.254.0.0/16)

IP address is detection picks up "169.254.x.x" addresses when there are interfaces with actual addresses configured down the list. The detection code incorrectly stops scanning when it encounters a link local address. It should instead of continuing to scan other interfaces for a "better" address.

It's quite normal to assign link local 169.254.x.x addresses to links that do not otherwise have a network address. Our code should skip addresses in this (169.254.0.0 - 169.254.255.255) range and move on to other interfaces. I ran into this on Windows but it probably can happen on any other platforms just as well.

Couchbase server ultimately fails to startup with the detected 169.254.x.x address.
