[poky] Systemd on Sumo without python3(runtime)

[matthew stanger]

Hi,

I'm having trouble removing python3 from being installed as a runtime
package using the Sumo branch. Per the systemd(v237) build
spec's(https://github.com/systemd/systemd/blob/v237/README) line 167
there isn't runtime requirements for python3, only build time.

It looks to me when running a .dot on the systemd dependencies that
python3 is being pulled in by 'meson' as a non'-native' dependency,
but this is where I'm lost. Could anyone clarify the logic here on how
to trim python3 to a native only dependency for systemd? Or is there
something fundamental I'm missing?

Cheers,
Matt
