logging in "lldb-server platform --server" does not work

Extended Description

The platform now does a fork() for every connection, but the logging infrastructure is not aware of that, which means the logs from individual processes get all mashed up.

Since the long-term idea for the platform is to handle each connection in a separate thread (instead of a process) I think we should bump the priority of that and then this issue will go away, since lldb knows how to do thread-safe logging.
