RFR [8046343] (smartcardio) CardTerminal.connect('direct') does not work on MacOSX

[Ivan Gerasimov]

Hello!

It was reported that trying to use DIRECT as the preferred protocol 
results in the CardException to get thrown under MacOSX.
It turn out to be a problem of pcscd-lite implementation of the API: 
 From the source code [1] it can be seen that the SCardConnect() 
function expects its argument dwPreferredProtocol to be non-zero.
Windows driver normally accepts zeros [2].

Could you please help review the fix?
