Weird.  examples/xml/nwfilter is the only subdirectory of examples/xml
that installs anything in the first place.  All other
examples/xml/*/*.xml files that get installed are done via the top-level
Makefile.am using a generic XML_EXAMPLES wildcard.  Maybe we just need
to remove examples/xml/nwfilter/Makefile.am and consolidate it into the
top-level alongside the other examples.

Meanwhile, I was looking whether examples/xml/storage/pool-netfs.xml
might be a case of something that is conditional on build flags (not all
libvirtd support netfs), and since that appears to be installed
unconditionally, that is another argument for making nwfilter examples
unconditional.

I also wonder if our current installation of examples/xml/** under the
libvirt-devel subpackage, instead of under the libvirt-docs subpackage,
makes sense.  Ultimately, it looks like this report has opened a can of
worms.
