[PATCH v3 09/10] qemu/uuid: Add UUID static initializer

[Jonathan Cameron via <qemu-devel@nongnu.org>]

From: Ira Weiny <ira.weiny@intel.com>

UUID's are defined as network byte order fields.  No static initializer
was available for UUID's in their standard big endian format.

Define a big endian initializer for UUIDs.
