tests/channel-helper: set blocking in main thread 

The /io/channel/command/echo tests run the reader side and the writer
side with the same underlying command channel. Setting the blocking mode
of the fd/handles while the other end is already reading/writing may
create issues (deadlock in win32 when earlier attempt of this series
were using SetNamedPipeHandleState). Let's just do it before spawning
the threads to avoid further concurrency issues.
