devshell.bbclass: fix double unbuffering

Browse Source 
stdout is already unbuffered in bitbake code. Attempt to
do it again in devshell.bbclass causes this crash when
running devpyshell:
  File "scripts/oepydevshell-internal.py", line 29, in <module>
      pty = open(sys.argv[1], "w+b", 0)
  IOError: [Errno 13] Permission denied: '/dev/pts/6'
