gpudev is a library that can be built without a gpu driver as all the other libraries
and it is actually used only in case of GPU memory mempool.

Reasons for this patch are:

- Have an upstreamed benchmark tool to measure network metrics using GPU memory
- Test some DPDK features not really tested anywhere like the external memory mempool feature
