Subject: [PATCH] yandex-music: workaround of release circle

The [repacker
project](https://github.com/cucumber-sp/yandex-music-linux) have release
circle with moving tags, which breaks package distribution in nixpkgs.
This replaces fixing revisions with hashes and implements automatically
counting of "rc" parts of version for case of moving tags.
