No missing-phase-hooks suggestion in buildPythonPackage

It like the missing-phase-hooks check might not be activated for buildPythonPackage: NixOS/nixpkgs#117614 (comment) (cc @sternenseemann)

Probably because buildPythonPackage passes checkPhase as installCheckPhase to mkDerivation. I wonder if we should use preCheck or preInstallCheck here.

We have overlays that specifically intercept buildPythonPackage, so we can simply do that. I think for users who don't know about how buildPythonPackage is internally implemented, they're more likely to expect their preCheck hook to run in the python checkPhase (whatever it's called inside mkDerivation being none of their concern).
