    imagebuilder: clean package_list
    
    commit 19ac879954 (imagebuilder: add package_list function) introduced
    a new function 'package_list' to the imagebuilder Makefile.
    Unfortunately the package list was poluted by stdout noise of the
    Makefile itself as well as opkg. Redirect those outputs to stderr to
    make sure that the package_list returned doesn't contain progress
    info output but really only packages.
