Add the fifolog tools to FreeBSD.

Quoth the man-page:

     Fifologs provide a compact round-robin circular storage for recording
     text and binary information to permanent storage in a bounded and pre-
     dictable fashion, time and space wise.

Not yet connected to the build, but feel free to test & review.
