[Pharo-project] AioPlugin and SqueakSSL plugin included in Cocoa (please test)

Hi, I added AioPlugin and SqueakSSL plugins in Cocoa builds. Aio tests in OSProcess are green, but some other fails, and I don't know the reason. Also, Zodiac tests are all green, but I think there are things missing. Can you test and provide feedback? link: https://ci.lille.inria.fr/pharo/job/Cog-VM/Architecture=32,OS=mac/lastSucces... Thanks, Esteban
