dev-libs/opensc: ship config snippet for app-crypt/p11-kit

In order to use smartcards with app-crypt/p11-kit, a module needs to be
loaded by it. Doing this makes sure "p11tool --list-tokens" will find
smartcards without further manual steps.
The method is inspired by Fedora and OpenSuse.

+# Doing it this way allows for packagers to package opensc for
+# 32-bit and 64-bit and make them parallel installable
