[#525] morph/container: Accept container session token in PutEACL

`SetEACL` method of latest `Container` contract accepts binary session token
as an argument.

Provide `SetEACLArgs.SetSessionToken` method. Accept session token as a
`[]byte` in `Wrapper.PutEACL` method and attach it to `SetEACLArgs`. Marshal
session token from container in `wrapper.PutEACL` function and pass it to
the method.
