[PATCH 2/2 V2] Kprobes: Build kretprobe examples only if arch supports kretprobes

[Ananth N Mavinakayanahalli]

From: Ananth N Mavinakayanahalli <ananth@xxxxxxxxxx>

This patch builds samples/kprobes/kretprobe_example.c only on archs that
support kretprobes. Thanks to Sam Ravnborg for Kconfig suggestions.
