[PATCH v1] app/testpmd: set srv6 header without any TLV

[Rongwei Liu <rongweil@nvidia.com>]

When the type field of the IPv6 routing extension is 4, it means
segment routing header.

In this case, set the last_entry to be segment_left minus 1 if the
user doesn't specify the header length explicitly.
