Subject: IPv6 setup: pass address prefix in separate dracut arg
References: bsc#1062026, bsc#1093795
Upstream: merged
Git-commit: c6fb83e6ebc310c615c145962f71b3f6f4819e88
    
Dracut distinguishes IPv6 addresses by bracket enclosing [1] so pass an
IPv6 address as such. The address prefix is passed separately through
netmask dracut argument (that is a slight misnomer as dracut just
propagates that value to iproute2 tools [2] which interpret it as
decimal number of prefix bits).
