    Fix platform restore to handle missing resolv.conf

    The resolv.conf file is no longer written to:
     /opt/platform/config/<ver>/resolv.conf

    It was removed from that location by:
    https://review.opendev.org/c/starlingx/config/+/856562

    Any backup taken after that commit merged will not
    contain the resolv.conf in that location, and any restore
    would fail.

    The resolv.conf is no longer needed at that location,
    so updating the restore code to no longer try to restore it
    from there.

    Test Plan:
      PASS - Perform a Backup / Restore of AIO-SX Debian
