Container contract checks signature of eACL iterating through keys
from neofsid contract.
Clients often ask eACL from storage nodes, but it's kinda hard for
them to check signature since they have no direct access to neofsid
contract. So the container contract can make one more iteration
through keys from neofsid contract and return suitable one.
