[PATCH 4/4] contrib: qemu-guest-agent.service: Use IgnoreOnIsolate=True

[Cole Robinson <crobinso@redhat.com>]

Changing runlevel (telinit 3) will stop qemu-guest-agent.service, and
it won't ever restart, because it's intended to only start when the
specified virtio device is added.

Use IgnoreOnIsolate=True plus Install WantedBy= to keep the agent
running regardless of runlevel, which is the expected behavior IMO.

This has been in RHEL since 7.2ish timeframe:
