add 'strip' install hook

Mostly a convenience for myself, and anyone else who runs builds of
things like util-linux or kmod, where having debug symbols on these
libraries can add a large amount of weight to the image.

+This hook will locate and strip binaries on your image before archival and
+compression. This hook should be last, as any binaries added to the image after
+this hook runs will not be stripped. This is mostly useful for users who run
+local debug builds but whom do not want or need the extra weight of debug
+symbols on their image.
