patch to upgrade rpm@4.4.5 to rpm@4.4.6

Folks-- New to the list, etc, etc. Attached is a patch to upgrade the port of rpm from 4.4.5 to 4.4.6 thus fixing the fact that it doesn't build. I also submitted the patch at: http://trac.macports.org/projects/macports/ticket/11580 but wasn't too detailed about the problems. Most of this patch deletes patches that were no longer used in the ports directory. Keith
