    util-linux: : use update-alternatives for fsfreeze, nsenter
    
    busybox may also provide a fsfreeze and nsenter implementation,
    so use u-a to allow installing them side by side.
    If one installs both, busybox and util-linux, one gets the following error
    (seen on a populate-sdk run):
    
    | ERROR: Postinstall scriptlets of ['busybox'] have failed. If the intention is to defer them to first boot,
    | then please place them into pkg_postinst_ontarget_${PN} ().
    | Deferring to first boot via 'exit 1' is no longer supported.
    
    And the coresponding do_populate_sdk extract:
    
    | ...
    | update-alternatives: Error: not linking ...sdk/image/usr/local/oecore-x86_64/sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/sbin/fsfreeze
    |     to /bin/busybox.nosuid /bin/busybox.nosuid since ...sdk/image/usr/local/oecore-x86_64/sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/sbin/fsfreeze
    |     exists and is not a link
    | ...
