Title: rename Thread backport ivar to not clash w/ rubinius locals (#11831)

Rubinius uses @locals on Thread for their Fiber locals. Since Rubinius, unlike CRuby
doesn't hide internal ivars, they can conflict with monkey patched ivars.
This namespaces the backported ivar so it is not the same as Rubinius's name.

See #11831 for context.
