tests: don't use "status" operand of dd in test-censor.t (issue6858)
Some implementations don't have this operand, let's just direct stderr into
/dev/null, that's pretty cross-platform.
Also specify bs=512 (the default for me), because the default might be
different on different systems. Other uses of dd in the tests do specify it, so
this is more consistent.
