pfPorts: Remove lzo2, directly use from FreeBSD ports

Our port was initially unmodified from FreeBSD ports, and then
only minimally diverged in terms of keeping up with upstream
libtool compatibility. It is required by the OpenVPN port.

Our local port was quite outdated (2.02 was from 2005) and the
plain FreeBSD port seems maintained, from now on, just let's use
theirs.

pfPorts: Remove lzo2, directly use from FreeBSD ports
pfPorts: Remove upload_progress_meter

A local port and source code that was found to not be in use by any
pfSense release back to 1.2. Has not been touched neither seemed to
be in use back to 2005.

Time to say good bye to this port, thank you Jeb for you
contribution back then.
