[gtk+/filechooserentry: 18/51] filechooserentry: Move _gtk_file_system_parse()

[Benjamin Otte <otte src gnome org>]

    filechooserentry: Move _gtk_file_system_parse()
    
    It's very specific to the file chooser entry, so it's better kept there.
    It's also not used anywhere else in the code.
