    Fix ubuntu-minimal to run autoremove

    The "ubuntu" target had a post-install 99-autoremove task that removed
    unnecessary dependency packages, but the "ubuntu-minimal" target does not.
    This patch moves the 99-autoremove post-install task from the "ubuntu" target
    to the "ubuntu-common" target so that both will run an autoremove at the end of
    the image build.
    For the Octavia amphora image, this saved about 1GB in the image by removing
    build only package dependencies.
