BestMatchPingerFactory returns NullPinger when better options are available

Description

In some cases the BestMatchPingerFactory may return the NullPinger, even when other options should work i.e. the necessary JNI bits for the JICMP pinger are available, and the JNA pinger is functional.

When using the NullPinger, all ICMP requests "fail".

Restarting the JVM restores the appropriate pinger.

PR for foundation-2017 should be building now: https://github.com/OpenNMS/opennms/pull/2310

I merged the PR that was targeted for foundation-2018, but looks like foundation-2017 may also be affected.

This works for me, and I've tried it on a couple of different systems (mac & linux) but I'd love a few folks to try it and let me know if they see any weirdness.

I know that our "get local host" sometimes gets the local non-loopback IP instead of the local loopback one.  Wonder if that's what's going on here.
