ifup-eth: apply PERSISTENT_DHCLIENT to IPv6 dhclient daemon
IPv6 dhclient daemon only tries one time to obtain a IPv6 address
from a DHCPv6 server regardless of the setting of PERSISTENT_DHCLIENT.
PERSISTENT_DHCLIENT option is only used for IPv4 dhclient daemon.
With the popularization of IPv6 protocol, some users prefer setting
IPv6 like IPv4. I think there are two solutions as follows,
1. adopt PERSISTENT_DHCLIENT option to both IPv4 and IPv6.
2. create a new option, such as PERSISTENT_DHCLIENT_IPV6 option,
just for IPv6.
The first solution does not introduce addition options, and the IPv4
and IPv6 settings are consistent. So I perfer choosing the first
solution.
Fixes: bf00a0048 ("Replace /var/run with /run everywhere")
