build: link DPDK libraries with --whole-archive

Browse Source 
The upcoming DPDK version adds objects that have no externally
referenced symbols but that must be linked in (specifically, the
default mempool handlers are now assigned by a constructor function).

Link all of the DPDK libraries with -Wl,--whole-archive to fix linking
against a static library build of DPDK.
