Updated gnupg21 to 2.1.13.

Noteworthy changes in version 2.1.13 (2016-06-16)
-------------------------------------------------

 * gpg: New command --quick-addkey.  Extend the --quick-gen-key
   command.

 * gpg: New --keyid-format "none" which is now also the default.

 * gpg: New option --with-subkey-fingerprint.

 * gpg: Include Signer's UID subpacket in signatures if the secret key
   has been specified using a mail address and the new option
   --disable-signer-uid is not used.

 * gpg: Allow unattended deletion of a secret key.

 * gpg: Allow export of non-passphrase protected secret keys.

 * gpg: New status lines KEY_CONSIDERED and NOTATION_FLAGS.

 * gpg: Change status line TOFU_STATS_LONG to use '~' as
   a non-breaking-space character.

 * gpg: Speedup key listings in Tofu mode.

 * gpg: Make sure that the current and total values of a PROGRESS
   status line are small enough.

 * gpgsm: Allow the use of AES192 and SERPENT ciphers.

 * dirmngr: Adjust WKD lookup to current specs.

 * dirmngr: Fallback to LDAP v3 if v2 is is not supported.

 * gpgconf: New commands --create-socketdir and --remove-socketdir,
   new option --homedir.

 * If a /run/user/$UID directory exists, that directory is now used
   for IPC sockets instead of the GNUPGHOME directory.  This fixes
   problems with NFS and too long socket names and thus avoids the
   need for redirection files.

   to retrieve the default package versions.

 * Fix detection of libusb on FreeBSD.

 * Speedup fd closing after a fork.
