veyron2/ipc: Invoker.Prepare will now return all tags associated with a
method, not just the security label.

This is primarily motivated by the goal of making security labels
"dynamic" (more discussion in:
https://docs.google.com/a/google.com/document/d/1DZUu2sGKrf-b4p9JFdIbN0ULhz9Loa8reuPNKsdMKD0/edit#
), however, the author feels that this commit is worthwhile regardless,
as it makes the power of method tagging in VDL more "accessible".
