Remove bitmap fonts from Build-Depends and use vector fonts only
AFAIK, LilyPond nowadays cannot and does not use bitmap fonts from X11.
Also:
- Add fonts-linuxlibertine because it is specifically used in the
UTF-8 snippet;
- Change fonts-freefont-ttf to fonts-freefont-otf as suggested in the docs;
- Remove fonts-ipafont-gothic because fonts-ipafont-mincho alone is used,
and, as a serif font, IPAMincho matches LilyPond's default fonts better.
Also, Build-Conflicts with fonts-noto-cjk which contains OpenType
Collection (OTC) fonts, which unfortunately Ghostscript does not yet
support and would cause the build to abort.
