[PATCH] xen/gen_hypercall: Leave a breadcrumb in xen-hypercall-defs.h

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

When Cscope-ing through Xen, one occasionally finds themselves in
xen-hypercall-defs.h and needing to find the originating file.

This is substantially magic, and even reading the Makefile that produces
xen-hypercall-defs.h is of little help if you're not aware of of the %.i : %.c
pattern rule, and that the header is generated from a .c file in practice.

No functional change.
