opensc: add PACKAGECONFIG for ctapi

Add a PACKAGECONFIG option for OpenSC's CT-API reader driver so it
can be enabled without modifying the recipe, e.g. from local.conf:

PACKAGECONFIG:pn-opensc = "ctapi"

Please note that OpenSC's configure allows only one reader driver:

Only one of --enable-pcsc, --enable-cryptotokenkit,
--enable-openct, --enable-ctapi can be specified!

So to use it, ctapi should replace the default pcsc rather than
being just added to it. Not enabled by default. Existing builds are
unaffected.

The patch also removes --disable-ctapi from EXTRA_OECONF.
