package/opensc: propagate dependencies from pcsc-lite

Commit d590003e31dd (package/pcsc-lite: needs gcc >= 4.9) propagated
that new dependency to a bunch of packages that select pcsc-lite.

Then commit 8aaa7ecbce1d (package/opensc: new package) introduced
opensc, which selects pcsc-lite. However, the package was submitted
before the dependency to gcc 4.8+ was added to pcsc-lite, and that was
missed during the review.

Add it now.
