Allow multiple crypto methods for file transfer session. HTCONDOR-233

Since the policy for the file transfer non-negotiated session is built
from the shadow config, rather than the startd's claimid, we need to
allow multiple crypto methods. Otherwise, if AES is the preferred
method, an old starter won't be able to connect and do transfers.
