Why doesn't USE_UNZIP use the base system unzip?

Simple because libarchive doesn't support all the infozip format yet.

My plan is to make USE_ZIP automatically use bsdtar (and not unzip so that
FreeBSD 8.x can get it) and introduce a new USE_INFOZIP for ports that won't
work with bsdtar.

I have a patch for this:

But I didn't get time to totally exp-run it yet.
