Add some missing getStablePtr()s for CAFs that the RTS refers to

A recent patch ("Refactor CoreArity a bit") changed the arity of
GHC.Conc.runSparks such that it became a CAF, and the RTS was not
explicitly retaining it, which led to a crash when the CAF got GC'd.
While fixing this I found a couple of other closures that the RTS
refers to which weren't getting the correct CAF treatment.
