[PATCH 1/1] kdump: append uts_namespace.name offset to VMCOREINFO

The offset of the field 'init_uts_ns.name' has changed
since commit 9a56493f6942c0e2df1579986128721da96e00d8.
Make the offset of the field 'uts_namespace.name' available
in VMCOREINFO because tools like 'crash-utility' and
'makedumpfile' must be able to read it from crash dumps.
