Issue 4987: Add Greek and Cyrillic glyph aliases

LilyPond default fonts (TeX Gyre) do not have Greek and Cyrillic glyphs.
New URW 35 fonts which are contained in Ghostscript 9.20 have them.

This commit makes that when you have the new URW fonts,
you can use their Greek and Cyrillic glyphs as default fonts.
