initrd: set ipv6.method=auto when the autoconfiguration field is 'none'

Browse source 
The 7th field of:

 ip=<client-IP>:[<peer>]:<gateway-IP>:<netmask>:<client_hostname>:<interface>:{none|off|dhcp|on|any|dhcp6|auto6|ibft}:[:[<mtu>][:<macaddr>]]

specifies which kind of autoconfiguration to do. 'none' and 'off' mean
static addresses.

The old network module of dracut used to leave kernel IPv6
autoconfiguration enabled when IPv4 static addresses were
configured. With NM, this corresponds to enabling IPv6 auto method.
