Clean up unnecessary function arguments 

Some of the inputs to some functions in the Altair validator guide
were required in earlier iterations of the aggregation scheme but are
no longer required in the current version. This commit cleans up these
functions.

##### Aggregation selection ##### Aggregation selection
A validator is selected to aggregate based on the computation in `is_sync_committee_aggregator` where `state` is a `BeaconState` as supplied to `get_sync_committee_selection_proof` and `signature` is the BLS signature returned by `get_sync_committee_selection_proof`. A validator is selected to aggregate based on the computation in `is_sync_committee_aggregator` where `signature` is the BLS signature returned by `get_sync_committee_selection_proof`.
The signature function takes a `BeaconState` with the relevant sync committees for the queried `slot` (i.e. `state.slot` is within the span covered by the current or next sync committee period), the `subcommittee_index` equal to the `subnet_id`, and the `privkey` is the BLS private key associated with the validator.
