Add a new testpmd pattern field 'last_rsvd' that supports the
last 8-bits matching of VXLAN header.
The examples for the "last_rsvd" pattern field are as below:
1. ...pattern eth / ipv4 / udp / vxlan last_rsvd is 0x80 / end ...
This flow will exactly match the last 8-bits to be 0x80.
2. ...pattern eth / ipv4 / udp / vxlan last_rsvd spec 0x80
vxlan mask 0x80 / end ...
This flow will only match the MSB of the last 8-bits to be 1.
