Rather than save the whole DPDK sources and build artefacts, checkout
sources in a separate directory and build DPDK there.
Only the installed artefacts are then going to the cache.
Example sources in the share/dpdk installed directory can be pruned too.
This makes a (v23.11-rc3) DPDK cache entry size go from ~120MB to ~7MB.
