Need to change response type to Access-Challenge from rlm_perl

Need to change response type to Access-Challenge from rlm_perl

To answer my own question, I found that using the return code RLM_MODULE_OK
triggers the server to respond back with Access-Accept. If I used
RLM_MODULE_HANDLED instead, the response packet type was set to what I
expected it to be. This makes sense since I expect the client to exchange
several messages with me before I finally trigger the Access-Accept message.
