meta/recipes-graphics/waffle: Add python3 dependency

The python3native.bbclass set PYTHON_{LIBRARY, INCLUDE_DIR} pointing to
python target build, a patch was add to use target _sysconfigdata too [1]
but is not available without python3 dependency.

Fixes waffle build when trying to find _sysconfigdata module,
