qt6.qtbase: set strictDeps, remove python3 from buildInputs to reduce closure size

python3 is references in the shebang of three scripts:

/nix/store/gbi67akslfd2n5d8q4vxpy8qzih31myl-qtbase-6.5.0
└───libexec/qt-testrunner.py: …#!/nix/store/fdqpyj613dr0v1l1lrzqhzay7sk4xg87-python3-3.10.10/bin/python3.# C…
    libexec/sanitizer-testrunner.py: …#!/nix/store/fdqpyj613dr0v1l1lrzqhzay7sk4xg87-python3-3.10.10/bin/python3.# C…
    mkspecs/features/uikit/devices.py: …#!/nix/store/fdqpyj613dr0v1l1lrzqhzay7sk4xg87-python3-3.10.10/bin/python3.# C…
    → /nix/store/fdqpyj613dr0v1l1lrzqhzay7sk4xg87-python3-3.10.10

All of them are normally not used in the build process of packages thus
the shebangs batching can be safely skipped.
