corosync.conf.example: change mcastaddr

Change suggested mcastaddr to one in the 239.255.0.0/16
pseudo-subnet. Multicast addresses outside 239.x.x.x may be IANA
registered and can clash with other services present on the
network. Suggest an address defined as part of the multicast IPv4
Local Scope in RFC 2365.
