samples: pktgen: add missing IPv6 option to pktgen scripts

[ Upstream commit 0f0c4f1b ]

Currently, "sample04" and "sample05" are not working properly when
running with an IPv6 option("-6"). The commit 0f06a678 ("samples:
Add an IPv6 "-6" option to the pktgen scripts") has omitted the addition
of this option at "sample04" and "sample05".

In order to support IPv6 option, this commit adds logic related to IPv6
option.

Fixes: 0f06a678
