Build a system Haiku package

* Create rules (build/jam/PackageRules) and a script,
  build_haiku_package, to build hpkg files.
* Move all rule invocations that copy files and created symlinks and
  directories in the "system" directory from HaikuImage to
  HaikuPackages, which creates a package "haiku.hpkg".
* build_haiku_image: Comment out adding the copyrights info to
  AboutSystem for the moment.
