Trampoline MessageReader::OnMessageDone() to correct thread.

This ensures that all socket operations occur on one thread, even when
MessageReader::message_received_callback_ punts its Task parameter onto another
thread.
Fixes a Host plugin crash on Linux during a remote desktop session.  In this
case, the problem was caused by EventExecutorLinux::Inject{Key|Mouse}Event()
doing the injection and the "done" task on a different thread.
