gnupg: fix smartcards (yubikeys) on Darwin
Since version 2.3, GnuPG no longer falls back to other access methods if
its built-in CCID driver fails to access smartcards, including yubikeys.

The built-in CCID driver fails on macOS.

The upstream developers recommend disabling CCID support in this case:

    If it works and the distribution doesn't offer appropriate USB
    configuration, I think that it's good for the distribution to use
    --disable-ccid-driver for building GnuPG.

The GNU Privacy Guard is the GNU project's complete and free
implementation of the OpenPGP standard as defined by RFC4880. GnuPG
"modern" (2.1) is the latest development with a lot of new features.
GnuPG allows to encrypt and sign your data and communication, features a
versatile key management system as well as access modules for all kind of
public key directories. GnuPG, also known as GPG, is a command line tool
with features for easy integration with other applications. A wealth of
frontend applications and libraries are available. Version 2 of GnuPG
also provides support for S/MIME.
