[gedit] desktop file: simplify

[Sébastien Wilmet <swilmet src gnome org>]

    desktop file: simplify
    
    - VERSION and FULL_LIBEXECDIR were not present in the *.desktop.in.in
    file. So rename the file to *.desktop.in, only the i18n.merge_file() is
    needed.
    
    - po_dir: the documentation says that it needs to be a relative path.
    - Avoid using the datadir global variable.
