Fixed Dialyzer specs

-------------------------------------------------------------------------
ssl's published documentation states:

   ssl_accept(ListenSocket) ->
   ssl_accept(ListenSocket, Timeout) -> ok | {error, Reason}

(see http://www.erlang.org/doc/man/ssl.html#ssl_accept-1)

while its code has the specs:

-spec ssl_accept(#sslsocket{}) -> {ok, #sslsocket{}} | {error, reason()}.
-spec ssl_accept(#sslsocket{}, list() | timeout()) -> {ok, #sslsocket{}} | {error, reason()}.

One of the two cannot be right.  This should be fixed.

Moreover, I do not see why the spec just mentions list() for the options when the documentation explicitly mentions the options of ssl.
