File valgrind.rename-HVMOP_inject_trap-struct.patch of Package valgrind

From: Olaf Hering <olaf@aepfle.de>

Subject: rename HVMOP_inject_trap struct

The implemented code to handle HVMOP_inject_trap handles the layout of
Xen 4.2. Rename the code accordingly. Since hvm_op is unversioned,
choose the Xen version as suffix.

Make it conditional on Xen 4.2 or later.
