print/lilypond: remove non-functional URW option

ChangeLog:
https://lilypond.org/doc/v2.24/Documentation/changes/index.html#notes-for-source-compilation-and-packagers

The possibility to bundle text fonts was removed by upstream. The URW option
therefore doesn't work anymore and might even result in a broken installation
when building with non-default options.
