Fix building the IPC fuzzer in light of the new Protobuf<->IPC bridge.

r321237 introduced a framework for sending protobuf messages over IPC in
chrome/common/safe_browsing. r321803 starting putting this new framework
to use. This change updates the ICP fuzzer's message_list so that it can
handle types that include protobuf messages.
