Update the FreeBSD GSG to cover installing from the pre-built package as
well as installing from a port.

Also, since the port is now based on meson, update the instructions for
compiling and running the example applications.

Note: at this stage, DPDK is in the "latest" package snapshot, but has
not yet made it's way into the quarterly snapshot used by default by
stable releases. This is hopefully only a matter of time.

 Compiling and Running the Example Applications

 When the DPDK has been installed from the ports collection it installs
