[libvirt] [PATCH] spec: require xen-devel for libxl driver

[Eric Blake]

When using 'rpmbuild --define "_without_xen"', but on a new enough
Fedora where %{with_libxl} still gets set to 1 by default, the
build dependencies were incomplete, which could result in 'make rpm'
failing because ./configure failed to build the libxl driver.

* libvirt.spec.in (BuildRequires): Fix xen-devel condition.

Pushing under the build-breaker rule.

I found this on a machine with 'xen-devel' uninstalled, while
running ./autobuild.sh; it took me a while to find the root
cause, since autobuild.sh uses 'rpmbuild --nodeps' and therefore
failed to tell me which packages I did not have installed.
