Generate libdpdk-dev dependencies and dpdk recommends

There are many, many binary packages in DPDK, and they constantly
change.
To avoid having to manually maintain the list of dependencies of
libdpdk-dev and recommends of dpdk, generate them at build time
depending on what is actually built for each architecture.
