The construction task did not provide much value while making it harder
to follow what happens in the code. Replacing it with a lambda closure.
This reduces the amount of arguments to keep track of and moves the
initialization code to the context of the VideoSendStream constructor.
A slight difference in behavior is that ownership of fec_controller
is kept in the VideoSendStream constructor scope until it is moved
in the initialization task. Since the construction waits for completion
of the task, this should not change any actual behavior.
