treewide: Use IN4ADDR_LOOPBACK_INIT more widely

We already define IN4ADDR_LOOPBACK_INIT to initialise a struct in_addr to
the loopback address without delving into its internals.  However there are
some places we don't use it, and explicitly look at the internal structure
of struct in_addr, which we generally want to avoid.  Use the define more
widely to avoid that.
