For support of Xen hypervisor live patching the hypervisor build id is
needed. Add a node /sys/hypervisor/properties/buildid containing the
information.

xen: add sysfs node for guest type2017-06-15T06:50:32+00:00Juergen Grossjgross@suse.com2017-06-14T15:12:45+00:00urn:sha1:4a4c29c96dde0eefd69054fd9e6b4255d4717799
Currently there is no reliable user interface inside a Xen guest to
determine its type (e.g. HVM, PV or PVH). Instead of letting user mode
try to determine this by various rather hacky mechanisms (parsing of
boot messages before they are gone, trying to make use of known subtle
differences in behavior of some instructions), add a sysfs node
/sys/hypervisor/guest_type to explicitly deliver this information as
it is known to the kernel.
