Subject: Add product identifying information to VMCOREINFO

Patch-mainline: Never, SUSE-specific

References: bsc#1123015

Since SUSE kernels sometimes backport patches that change the structures

required to save a dump file using makedumpfile, it is necessary to recognize

such a patched kernel from a vanilla kernel in the kdump environment. The

VMCOREINFO note is perfect for this purpose.
