We only revert sip and pyqt, python update is good t have as it adds more
stability on arm builds. The issues that need to be resolved before
updating sip and pyqt:

- On arm pyqt causes
t.qpa.openglcontext: Could not create NSOpenGLContext with shared context, falling back to unshared context.
UNSUPPORTED (log once): POSSIBLE ISSUE: unit 0 GLD_TEXTURE_INDEX_2D is unloadable and bound to sampler type (Float) - using zero texture because texture unloadable
- pyqt-builder fails on detecting sip as dependency on setuptools build
(We fixed this by removing deps on pyqt-builder package)
- Also for some reason sip env fails on krita build phase breaking the
nighties.
