Use meson to build port_info_app

Adding a meson.build file for the port_info_app. This application is a
dpdk app that queries the dpdk ports for its MAC address. That MAC
address will then be stored in rapid.env. If needed, it will then be
used by PROX e.g. in l2 test cases.
The app is only used if the vim parameter in the rapid.env file is set
to kubernetes. In case of OpenStack, the MAC address is obtained through
the heatclient API, see stackdeployment.py for more details.
