    main: fix program name in `gedit --help` output
    
    The output was:
    ```
    $ gedit --help
    Usage:
      org.gnome.gedit [OPTION…] [FILE…] [+LINE[:COLUMN]]
    [...]
    ```
    
    There was a comment that links to a blog post. After reading the blog
    post, I don't think gedit needs it, because everything has the
    'org.gnome.gedit' ID/basename: the *.desktop file, the icon, the
    GApplication ID.
    
    If calling g_set_prgname() is really needed, then it needs to be done at
    a different place, to not break `gedit --help` for normal usage, and not
    break all the calls to g_get_prgname().
