waf: don't assume the waf intepretter is good
Waf typically uses `python` as the intepretter but inside a task this does not exist. Typically this is solved by patching waf (see the glmark2 recipe) but not all versionf of Waf support Python 3 so we can't assume a specific interpretter. Instead, create a new variable WAF_PYTHON for the correct interpretter, and default this to `python3`. If the user has a recipe that needs Python 2 then this can be changed in the recipe.
