Some python packages (e.g. functools32) are conditionally disabled for certain interpreter versions by having them return null instead of a derivation. `getRecursivePropagatedBuildInputs` fails if such a package is part of the dependency tree. This commit makes it only recurse into derivations and ignore everything else. This also deduplicates the final plugin list to improve startup time.
