spec: Add runtime requirement for libssh2
spec: Add runtime requirement for libssh2

libssh2 unfortunately doesn't support symbol versioning so RPM can't
figure out what version is needed for the currently installed libvirt
package. This patch adds a runtime requirement, so that the correct
version of libssh2 can be installed along with libvirt.
