distro/redhat: fix rpmlint warnings

* quagga.spec.in: Use %global when defining globals inside conditional
  blocks.
  Comment Obsoletes as rpmlint wants specific versions. The packages are
  long gone, but leave as historical documentation.
  Don't use %version in changelog entries, or other live macros.
  Fix spaces-for-indent everywhere, use tab (sorry spaces people).
