coreos-cloudinit: fix hostname reset bug
When coreos-cloudinit runs on a platform where afterburn sets the hostname it would reset the hostname to localhost. Fix that bug, by checking that the hostname is non-empty before applying. Pulls in flatcar/coreos-cloudinit#25.
See: flatcar/Flatcar#1262
How to use
Boot built image on Azure without providing any userdata to see if the hostname gets reset.
