beos: Fix replicants 

Waiting on the semaphore was not enough, it was causing a crash on
replicant removal. Now we wait for the replicant main thread to exit.
It fixes replicants, at least when a single one is used per application.
Using more than one still causes issues due to some libs not liking
being used twice (hlcache it seems).
