netmap: Reinstate and update netmap plugin

Thet netmap plugin was moved to depreciated in commit 998b8fe.

On FreeBSD netmap offers a natively supported kernel interface for
userspace networking and enables VPP without the use of DPDK.

Reinstate the netmap plugin and adapt it to the newer plugin interface.
