Updated gnutls to 3.5.13.

While here, remove empty line from PLIST.

* Version 3.5.13 (released 2017-06-07)

** libgnutls: fixed issue with AES-GCM in-place encryption and decryption in
   aarch64. Resolves gitlab issue #204.

** libgnutls: no longer parse the ResponseID field of the status response
   TLS extension. The field is not used by GnuTLS nor is made available to
   calling applications. That addresses a null pointer dereference on server
   side caused by packets containing the ResponseID field. Reported
   by Hubert Kario. [GNUTLS-SA-2017-4]

** libgnutls: tolerate certificates which do not have strict DER time encoding.
   It is possible using 3rd party tools to generate certificates with time fields
   that do not conform to DER requirements. Since 3.4.x these certificates were \ 
rejected
   and cannot be used with GnuTLS, however that caused problems with existing private
   certificate infrastructures, which were relying on such certificates (see gitlab
   issue #196). Tolerate reading and using these certificates.

** minitasn1: updated to libtasn1 4.11.

** certtool: allow multiple certificates to be used in --p7-sign with
   the --load-certificate option. Patch by Karl Tarbe.
