sigmoid cross-entropy loss: ignore selected targets by `ignore_label`

sig-ce learns to ignore by zeroing out the loss/diff at targets equal to
the configured `ignore_label`.

n.b. as of now the loss/diff are not properly normalized when there are
ignored targets. sig-ce loss should adopt the same normalization options
as softmax loss.
