[libvirt] [PATCH] build: fix regression with libvirt-api.xml generation

[Eric Blake]

(EXTRA_DIST): Remove redundant listing of xml files.
(html/%-%.html, html/%-virterror.html, %-api.xml, %-refs.xml):
Rewrite with...
(python_generated_files): ...new macro, since make didn't see
through the dependency chain correctly otherwise.

Since I'm not going to get the xsltproc stuff fixed today, but the
broken python bindings are still annoying, I'm splitting this into
a smaller patch.  This does not fix VPATH builds (but that is no
change in the status quo), but DOES fix libvirt-api.xml dependency
detection, so that touching include/libvirt/libvirt.h.in will once
again reflect all the way to python bindings during 'make all'.
