doc: Update DPDK pdump documentation
The DPDK pdump sample app was renamed from 'dpdk_pdump' to
'dpdk-pdump'. Update references to same within
INSTALL.DPDK-ADVANCED.md.
Add an additional sample command line that shows how to capture all
traffic traversing an interface within a single pcap file - a useful
tool for debugging DPDK-related issues.

Then, navigate to the 'app/pdump' directory in DPDK, 'make' the application and run like so: ``` -sudo ./build/app/dpdk_pdump -- +sudo ./build/app/dpdk-pdump -- --pdump port=0,queue=0,rx-dev=/tmp/pkts.pcap --server-socket-path=/usr/local/var/run/openvswitch ``` The above command captures traffic received on queue 0 of port 0 and stores it in /tmp/pkts.pcap. Other combinations of port numbers, queues numbers and -pcap locations are of course also available to use.
