Fix longname-mode on hosts without detectable FQDN
Server startup and CLI tools fail in longnames-mode if erlang is not
able to determine host FQDN (with at least one dot in it).
E.g. this can happen when you want to assemble a cluster using only
IP-addresses, and you completely don't care about FQDNs.
And it was not possible to alleviate this situation using any options
from http://erlang.org/doc/apps/erts/inet_cfg.html
Fixes #890
