buildPython*: remove pythonRecompileBytecodeHook as dependency

This hook was added to get reproducible bytecode. Because it was causing
issues it was disabled, but still kept as a dependency. Now the main
issue with bytecode reproducibility has been resolved by updating pip to
20.2.4, we remove this hook as a dependency.

If a package with Python code is not yet reproducible, one could add
this hook to `nativeBuildInputs`.
