[libvirt] [PATCH 2/4] maint: start factoring bootstrap



Borrow ideas from gnulib/build-aux/bootstrap, in order to factor the
specifics of libvirt into bootstrap.conf, while allowing future
upgrades of bootstrap to happen with less effort.

* bootstrap (gnulib_tool): Update invocation to be closer to
gnulib's version.  Move libvirt specifics...
* bootstrap.conf: ...into new file.
---

All manual edits at this point, but it creates a bootstrap.conf
similar to the template in .gnulib/build-aux/bootstrap.conf.
