Remove unused generation of Request Authenticator in Account-Request

Do not generate an unused and invalid Request Authenticator (random
value) when constructing Accounting-Request packets. The correct Request
Authenticator is calculated subsequently in radius_msg_finish_acct()
using MD5(msg + shared secret).
