beauty-line-icon-theme: 0.0.1 -> 0.0.4

Update to the latest upstream release:
https://github.com/gvolpe/BeautyLine/releases/tag/0.0.4

Includes some refactoring:
- use stdenvNoCC instead of stdenv
- use fetchFromGitHub instead of fetchzip for fetching the release from
  GitHub
- the newest release is located in the subdirectory BeautyLine-V3, so we
  fetch only this folder via sparseCheckout and set it as source root
- run preInstall and postInstall hooks in the installPhase
- deduplicate files with jdupes
- set dontPatchELF and dontRewriteSymlinks to true. These fixup steps
  are slow and unnecessary for this package.
