parser: Do now allow the empty symbol declaration An empty element is allowed in SymbolsBody definition, so the following keymap is gramatically correct. ``` xkb_keymap { ... xkb_symbols "sym" { key <SPC> {, [Space] }; }; }; ``` However, the current parser crashes with the keymap due to null pointer access. This change fixes it by changing the parser not to allow it.
