fix(ceilometer): Libvirt connectivity for Epoxy (#185)

* fix(ceilometer): Add required packages for Epoxy

Ceilometer is complaining via traceback that python-libvirt is not
installed so let's install it.

* chore(ceilometer): Remove unnecessary build pkgs

Drop packages not required for building ceilometer or its dependencies:
bash, brotli, docutils-common, gettext, libjs-sphinxdoc, libjs-underscore,
libvirt0, ssl-cert, xmlsec1
