Fix client only RPM build & other misc RPM problems

* libvirt.spec.in: Remove obsolete --with-remote-pid-file arg.
  Add missing %{without_libxl} statement. Fix handling of docs
  in client only build. Put systemtap files in -client RPM
  instead of -daemon RPM
* examples/xml/nwfilter/Makefile.am: Don't install examples if
  nwfilter is disabled.
