Move TUI back to main package
    
    The TUI bits were inadvertently(?) moved to the -gui subpackage
    in the 0.46-1 package build. This broke Rawhide composes, as it
    made anaconda's text interface require python3-meh-gui. This
    moves the TUI bits back to the main python3-meh package and
    should fix Rawhide composes.
