[PATCH 2/2] app/testpmd: use flags from user if it is set

["Minggang Li(Gavin)" <gavinl@nvidia.com>]

It's user's responsibility to set correct flags, especially the G bit, to
distinguish the protocols, VXLAN and VXLAN-GBP, sharing the same port 4789.

It will be set to 0x8 if user does not specify the flags.

Fixes: da118115d95c ("app/testpmd: support matching any VXLAN field")
