[OE-core] [PATCH] meta/classes/meson.bbclass: Add inherit setuptools3

[Alexander Kanavin]

I tend to agree with Khem; this change will pull in target python as build
and runtime dependency to all meson-using recipes, even those that have
nothing to do with python.

I'd suggest you fix the broken recipes individually by adding python3 to
DEPENDS. Yes, the "not a valid python" message is not helpful; suggestions
how to improve this are welcome.
