meta-lxatac-software: tacd{,-webinterface}: update

This adds the following new features:

  - Retry polling for update bundles with exponential backoff.
    This solves a problem where the first update poll after bootup is
    likely to fail, because the network is not yet up, and the next one
    only takes place hours or days later.

  - Improved error handling in the iio/dut power threads.

  - Use the modern InstallBundle and InspectBundle RAUC DBus APIs
    instead of the deprecated Install and Info APIs.

  - Updated rust dependencies.

  - A diagnostics screen that displays a lot of information on a single
    screen and provides a border that can be used to align the
    LCD.
    It also allows toggling the LEDs and backlight to make sure they
    work correctly.

  - Notifications in the web interface that redirect the user to
    appropriate command lines when they try to change the active RAUC slot
    or enable/disable update channels in the web interface.

  - A /etc/motd that is updated in realtime with relevant information
    about the TAC.

  - A web view of the software packages and licenses that make up the
    meta-lxatac image.
