ractor: don't inherit the default thread group
[Bug #17506]
Thread.current.group isn't shareable so it shouldn't be inherited by the main thread of a new Ractor.
Thread.current.group
This cause an extra allocation when spawning a ractor, which could be elided with a bit of extra work, but not sure if it's worth the effort.
