File suse-bump-xen-version.patch of Package libvirt.16761

Bump minimum supported Xen version to 4.9

There were no changes to the libxl API between 4.8 and 4.9, so
the LIBXL_API_VERSION is set to 0x040800.

Note: xen.git commit c3999835df is needed in any Xen package where
this patch is expected to work. It is included in Xen 4.13, but would
need backporting to anything older. The dependency on xen.git commit
c3999835df makes it hard to upstream this patch.

See bsc#1157490 and bsc#1167007 for more details
