    bash completion: Restore completion for 'guix system', etc.
    
    Commit 538ca8dd65f0075cc65bcca18ed87f66a789290a introduced a second
    '_guix_complete_subcommand' function, shadowing the existing one, which
    broke sub-command completion for 'guix system', 'guix import', etc.
    
    * etc/completion/bash/guix: Distinguish between '_guix_complete_command'
    and '_guix_complete_subcommand'.  Adjust users to call the right one.
