util: forward __bool__()/__nonzero__() on fileobjectproxy

In trying to debug the Windows process hang in D2720, I changed the stderr pipe
to the peer to be os.devnull instead.  That caused sshpeer._cleanuppipes()[1] to
explode, complaining NoneType has no __iter__ attribute, even though the
previous line checked for None.
