[gtk/builder-precompile: 1/5] builder: Use a better name for templates

    builder: Use a better name for templates
    
    This name can show up in error messages or profiler
    traces, so it is nice to provide some hint what
    file we are dealing with.
    <GtkFileChoser template> is a lot more helpful
    than <input>.
