Can we also remove this flag from runtest.py?

Consider verifying that nothing internal depends on that. Quick check on
cs.chromium.org shows ecs was the only thing in public repos.

Done.

I ran `fgrep 'no-spawn-dbus' . -rsnI` in build_internal and confirmed that only
ozone_ecs recipes use this option.

Do I need to take care below?
