[PATCH v2 2/2] tools/x86: move arch-specific include/xen/ population into arch-specific rule

[Jan Beulich <jbeulich@xxxxxxxx>]

There's no need for the common "xen-dir" rule to have an arch-specific
part when there already is a arch-specific rule where this can be taken
care of (arguably instead of all-y this might better be xendir-y
anyway).

Also change the pattern from *autogen.h to *-autogen.h.

v2: Insert dash in pattern. Re-base over changed earlier patch.

I was tempted to move the "xen-dir" dependency from all-$(CONFIG_X86) to
the general all-y, but perhaps that's less related and hence should
really be a separate change (and there may also be arguments against
that).
