Fix delay-based attestation inclusion reward
Modify the delay-based reward function from the current `r = (65-d)/64` to `r = 1/d`.

Rationale is that in the normal case delay is close to 1, so we want a larger incentive to get included more quickly to encourage stability of the fork choice. Particularly, in the status quo if you know that you will be a proposer <4 slots in the future, you can maximize earnings by delaying inclusion of your attestation until you can include it yourself and get the proposer reward; this adjustment fixes this in the normal case.
