Add support for "lzma alone" compression format (lzdio)

- "lzma alone" is superseeded by XZ but it's used by Suse and Mandriva
  distros so it's nice to have as it doesn't need much, only open differs
  from XZ
- rpmlib() dependency versions are an uuuuuuuugly mess here: Suse used
  "PayloadIsLzma = 4.4.2-1" so that's what we provide to be most compatible
  (hopefully). Built packages require "PayloadIsLzma <= 4.4.6-1" however
  to be compatible with Mandriva 2008.0. Did I already say it's ugly?
- Based on similar patch in Mandriva by Per Øyvind Karlsen, but avoiding
  unnecessary renames in rpmio
