OmapiCallbackHandlerVpcd: fetch SELECT response from OMAPI

At the moment we get the select response by selecting 7FFF, which
is an alias for the currently selected application. This returns a
select response when an ISIM or USIM application is selected. Other
applications may react differently here.

OMAPI has a getSelectResponse method through which we can get the
actual response that was received from the card when the application
was selected when openLogicalChannel was called. This is far more
accurate, so lets use getSelectResponse instead of selecting 7FFF.
