dpdk: use vpp physmem allocator for dpdk buffers
This allows us to have single contignuous allocation for DPDK buffers
with single mmap FD, so buffer memory can be easily shared with diffrent
process.
As a consequence dpdk socket-mem is no longer in charge for allocating
buffer memory, but still we need some space allocated for dpdk
structures so default socket-mem is reduced form 256 to 64 MB.
For a default of 16K buffers per numa node, physmem allocation is now
40MB, so basically this change reduces footprint from 256MB per socket
to 48 (64 + 40).
