concurrencytest: Fix Python3 warning
This gives a warning in some situations:
File "tools/dtoc/../concurrencytest/concurrencytest.py", line 95,
in do_fork
stream = os.fdopen(c2pread, 'rb', 1)
File "/usr/lib/python3.8/os.py", line 1023, in fdopen
return io.open(fd, *args, **kwargs)
RuntimeWarning: line buffering (buffering=1) isn't supported in binary
mode, the default buffer size will be used
Fix this by dropping the line-buffer parameter.
