zafiro-icons: 1.1 -> 1.2

Update to the latest upstream release:
https://github.com/zayronxio/Zafiro-icons/releases/tag/1.2

Includes some refactoring:
- use stdenvNoCC instead of stdenv
- 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.
- remove single file with problematic filename causing
  gtk-update-icon-cache to fail
