    sysupgrade: create 10_disable_services w/ fixed modified time
    
    Every time "sysupgrade -b -" runs it would generate a new
    (synthetic) "/etc/uci-defaults/10_disable_services" file with
    the current time as the modified time.  This unfortunately
    creates a non-deterministic tarball, so if you run a cron job
    to save your state, you don't have a trivial way of seeing if
    it changed or not without unpacking the archive, deleting this
    file, and comparing the entire directory tree to the previous
    backup.
    
    Fixes: #16145
    Fixes: 0ad062a21b ("base-files: sysupgrade: include uci-defaults script disabling services #2")
