Use correct lower bounds for geometric distribution bucketers in the new protos.

The old protos said that the underflow bucket was [-Inf, 0) and the first
finite bucket was [0, 1).  The new protos say the underflow bucket is
[-Inf, 1), but the code was never updated to do that, so we've been sending
incorrect distributions to the new API.
