lilypond: update to 2.19.84
https://github.com/void-linux/void-packages/pull/18965

Description:
Compiled for and tested on x86_64, x86_64-musl, i686, armv7l; no problems.
Packages also built sucessfully for aarch64 and armv6l.

Due to its ten thousand files lilypond-doc will exceed maximum log length, but I didn’t encounter any problem locally.
