    automation: Switch arm32 cross builds to run on arm64
    
    Due to the limited x86 CI resources slowing down the whole pipeline,
    switch the arm32 cross builds to be executed on arm64 which is much more
    capable. For that, rename the existing debian container dockerfile
    from unstable-arm32-gcc to unstable-arm64v8-arm32-gcc and use
    arm64v8/debian:unstable as an image. Note, that we cannot use the same
    container name as we have to keep the backwards compatibility.
    Take the opportunity to remove extra empty line at the end of a file.
    
    Modify the tag of .arm32-cross-build-tmpl to arm64 and update the build
    jobs accordingly.
