Cleanup sysroot_scripts

- Remove UpdatePackageLists* since this functionality was already performed by
  BuildSysroot*.
- Remove the "Revision" key from sysroots.json since the "Sha1Sum" key is enough
  to uniquely identify each sysroot.
- Move packagelist.* into generated_package_lists/*.  There were at least 2
  occasions where folks tried to manually update these files.
