 rts/RetainerProfile: Adding missing closure types to isRetainer

 orzo in `#ghc` reported seeing a crash due to the retainer profiler
 encountering
 a BLOCKING_QUEUE closure, which isRetainer didn't know about. I performed
 an
 audit to make sure that all of the valid closure types were listed; they
 weren't. This is my guess of how they should appear.

 Test Plan: Validate
