pcp updates: INADDR_LOOPBACK for ipv6

[Dave Brolley <brolley@xxxxxxxxxx>]

Nathan spotted this one:

# netstat -tulnp | grep pmcd
tcp        0      0 0.0.0.0:44321           0.0.0.0:*               LISTEN      
21341/pmcd
tcp6       0      0 :::44321                :::*                    LISTEN      
21341/pmcd

# vi /etc/sysconfig/pmcd
(uncomment PMCD_LOCAL=1 )

# service pmcd restart
Redirecting to /bin/systemctl restart  pmcd.service

# netstat -tulnp | grep pmcd
tcp        0      0 127.0.0.1:44321         0.0.0.0:*               LISTEN      
6595/pmcd
tcp6       0      0 :::44321                :::*                    LISTEN      
6595/pmcd


The listening address of ipv6 with PMCD_LOCAL=1 should be ::1:44321. 
OpenRequestSocket() was not setting up the listening address properly.  
Fixed by this commit which has been pushed.
