    run-postinsts: Print message before running deferred postinst scripts
    
    Opkg can defer running postinst scripts to first boot, which can take
    a while on some systems. The output of `opkg configure` (or whatever pm
    is used) is redirected to a file when logging is enabled
    (I.e. $POSTINST_LOGGING == 1), making the machine appear hung during
    this process. This change simply prints a wait message on the console
    to inform the user of this potentially long and silent operation so
    that they do not mistakenly reboot their machine.
    
    Why not simply `tee` the output instead?
    Tee might be provided by BusyBox in some distros, which may need to run
    update-alternatives in the very postinst scripts being executed by this
    process. It's therefore not safe to assume Tee (or any other packaged
    util) is available until the configure process finishes.
