Move all documentation into a -docs sub-RPM

Currently documentation is split between the libvirt RPM and the
libvirt-devel RPM. In the client-only build there is no libvirt
RPM, so the docs need to live elsewhere. The obvious answer is a
dedicated libvirt-docs RPM. For back-compatibility make the
libvirt-devel RPM require the libvirt-docs RPM

* libvirt.spec.in: Create separate libvirt-docs RPM
