Some other projects using meson may not be able to use DPDK
using the standard distribution pkg-config mechanism.
Meson supports a way to handle this via the subproject
  https://mesonbuild.com/Subprojects.html

This patch adds the necessary depedency to follow the
"Naming convention for depedency variables" from the documentation.
It has no impact if subproject is not being used.
