Revert "fdo#67862: Add greek symbols to docking window"

This partially reverts commit e9a7ff1a5ba9d5ba34eeca9d622d8a3a9c68ade8.

Leave the SAL_N_ELEMENTS changes in.

I forgot about the translation of those symbol names. The en-US %alpha is
%alfa in pt-br. See starmath/source/symbol.src. One list get's translated,
the other not.

For UI purpose GetUiSymbolName gives the tranlated one and for export
GetExportSymbolName gives the untranslated english string.

Feel free to implement this or maybe drop the translation of those symbols.
