    flatpak: Fix the build on Aarch64
    
    The mtools release is old and predates the Aarch64 support in the
    autotools.
    
    As a result, the included config.{guess,sub} files do not know about the
    Aarch64 architecture, and the build fails.
    
    This commit takes some newer config.{guess,sub} files which the Sdk
    helpfully provides for exactly this purpose.
