    base-file: remove password aging feature form /etc/shadow
    
    In the default shadow file, as visible in the failsafe mode, the user
    root has value of `0` set in  the 3rd field, the date of last password
    change. This setting means that the password needs to be changed the
    next time the user will log in the system. `dropbear` server is ignoring
    this setting but `openssh-server` tries to enforce it and fails in the
    failsafe mode because the rootfs is R/O.
    
    Disable the password aging feature for user root by setting the 3rd
    filed empty.
