feat(tvix): Implement all remaining RPC calls r/1622

Implement all remaining RPC calls on the RpcSstore client, remove a few
stub methods we had added that weren't actually present in the old
RemoteStore implementation, and add one more RPC call for getBuildLog
that is present in the store API, but that we hadn't added as a
stub *or* to the proto.

Fixes: #29
