RFR 8059212: Modify sun/security/smartcardio manual regression tests so that they do not just fail if no cardreader found

[Ivan Gerasimov]

We've got a request to modify the smartcardio-related regtests so that 
they'll be more convenient to use.

Konstantin, could you please confirm this will work for you?
