rts: Fix compaction of SmallMutArrPtrs
This was blatantly wrong due to copy-paste blindness:
* labels were shadowed, which GHC doesn't warn about(!), resulting in
plainly wrong behavior
* the sharing check was omitted
* the wrong closure layout was being used
Moreover, the test wasn't being run due to its primitive dependency, so
I didn't even notice. Sillyness.
Test Plan: install `primitive`, `make test TEST=compact_small_array`
