app/testpmd: support IPv6 fragment extension item

rte_flow update, following RFC [1], added to ethdev the rte_flow item
ipv6_frag_ext.
This patch updates testpmd CLI to support the new item and its fields.

To match on fragmented IPv6 packets, this item is added to pattern:
... ipv6 / ipv6_frag_ext ...
