[libvirt] [PATCH] libxl: libxl_domain_create_restore has an extra argument

In the latest libxenlight code, libxl_domain_create_restore accepts a
new argument. Update libvirt's libxl driver for that. Use the macro
provided by libxenlight to detect which version should be used.

The new parameter (send_back_fd) is set to -1 because libvirt provides
no such fd.
