[oe] [PATCH] Fix busybox SUID support

[Tom Rini]

I was about to just push this and I noticed that a number of
distributions (SlugOS, Angstrom, Kaelios, micro) currently set
FEATURE_SUID=y, but it's not actually install SUID.  And since I recall
some way-back-when's of "busybox SUID is dangerous / crap!", I thought
it best to post the patch first and let folks speak up / ask me to drop
FEATURE_SUID=y when I do this.  So, here's the patch:
