Using ${IMAGE_FEATURES} in a package postinst is pretty unwholesome.  If
you do:

$ IMAGE_FEATURES=debug-tweaks bitbake openssh
$ sleep $[21*86400]
$ IMAGE_FEATURES=no-debug-tweaks bitbake my-production-image

then there is a significant risk that you will accidentally get the
insecure openssh in your image without realising it.

I know dropbear does this sort of thing already but we should really try
not to add more of that stuff.  If it's an IMAGE_FEATURE then it should
really be getting handled at the rootfs level, not burned into the
packages in the feed.
