listen: bind() failure on secondary address is non-fatal
Several users had problems with binding MPD to "localhost". The cause was duplicate /etc/hosts entries: the resolver library returns 127.0.0.1 twice, and of course, MPD attempts to bind to "both" of them. This patch makes failures non-fatal, given that at least one address was bound successfully. This is a workaround; users should rather fix their /etc/hosts file.
