update/traffic: fix IPv6 translation

[rzalamena]

Fix the following configuration parsing error:

configuration | error message: illegal IP address string passed to inet_pton

[rzalamena]

This partially fixes #927 for ExaBGP 4.2.

Hi @rzalamena - this patch looks good, how did you test it please ?

[rzalamena]

@thomas-mangin using the configuration file from issue #1004 .

neighbor 10.0.1.1 {
router-id 10.0.1.101;
local-address 10.0.1.101;
local-as 100;
peer-as 100;
flow {
route {
match {
source 1.1.1.2/32;
destination 3.3.3.3/32;
packet-length <200;
}
then {
redirect 50.0.0.2;
rate-limit 55;
}
}
#end route 1
route {
match {
source 1::2/128/0;
destination 3::3/128/0;
packet-length <200;
}
then {
redirect 50::2;
rate-limit 55;
}
}
#end route 2
}
}

This line redirect 50::2; causes the parse failure.

Thanks for the quick responses!
