nativesdk-python*: suppress user site dirs
Currently, $HOME/.local is being added into sys.path in the Python SDK
causing subtle host contamination. Suppress this by exporting
PYTHONNOUSERSITE = "1" as documented in PEP 370.
This issue occurred in the past for python*-native and was fixed
similarly in OE-core commit
8fe9fb4d5a61dcbcb3fc5b9ee0234cc135af873f
("python*native.bbclass: suppress user site dirs").
