[libvirt] [PATCH 1/3] libxl: switch to using libxl_domain_create_restore from v4.4 API

In LIBXL_API_VERSION 0x040400, the libxl_domain_create_restore API gained a parameter for specifying restore parameters. Switch to using version 0x040400, which will be useful in a subsequent commit to specify the Xen migration stream version when restoring.
