libvirt.spec.in: use explicit --with-xxx for all features
libvirt.spec.in: use explicit --with-xxx for all features

Rather than letting the configure script auto-detect features
we expect, use --with-xxx to explicitly mandate them. This
ensures that we get an error upfront when running configure,
rather than a failure later during build or RPM file packaging
time.
