platform,core: better handle onlink flag for ECMP routes 
The onlink flag is part of each next hop.

When NetworkManager configures ECMP routes, we won't support that. All
next hops of an ECMP route must share the same onlink flag. That is fine
and fixed by this commit.

What is not fine, is that we don't track the rtnh_flags flags in
NMPlatformIP4RtNextHop, and consequently our nmp_object_id_cmp() is
wrong.

libnm-platform

A static helper library that provides NMPlatform and other utils. This is NetworkManager's internal netlink library, but also contains helpers for sysfs, ethtool and other kernel APIs.

NMPlaform is also a cache of objects of the netlink API: NMPCache and NMPObject. These objects are used throughout NetworkManager also for generally tracking information about these types. For example, NMPlatformIP4Address (the public part of a certain type of NMPObject) is not only used to track platform addresses from netlink in the cache, but to track information about IPv4 addresses in general.

This depends on the following helper libraries
