    gnu: criu: Reset timestamps in .egg file.
    
    Ensure all files being built are dated no earlier than 1980 by copying in a
    modified (@@ (guix build python-build-system) ensure-no-mtimes-pre-1980) 
which
    is symlink-aware. This copy should be removed when the original procedure is
    modified to avoid calling UTIME on symlinks.
    
    * gnu/packages/virtualization.scm (criu)[arguments]: Add
    'ensure-no-mtimes-pre-1980' phase.
    [inputs]: Remove python.
    [native-inputs]: Add python-toolchain.
