lib/oe/package_manager: remove package feed lists

Remove opkg package feed lists after generating the rootfs. The
lists have been generated by the local feed but are no longer
necessary after image generation. This still leaves the package
management fully usable (and hence is different from omitting
package-management from IMAGE_FEATURES).
