    linux-firmware: update to current Git head
    
    Update the linux-firmware package in order to force the buildbots to fetch the
    proper mirrored version.
    
    Currently each builder has its own copy of the linux-firmware checkout staged
    in its own dl/, since the package was updated before the mirrored copy has
    been uploaded. The builders then subsequently uploaded their own copy instead,
    leading to md5sum mismatches since each clone produces different tarballs.
    
    By bumping the package to a new version and uploading the mirrored archive
    with the proper md5sum beforehand, the builders will fetch that instead and
    not upload their own copies.
    
    To properly solve that problem in the future we need to ensure that packed
    checkouts become reproducable.
