tor: security bump to version 0.2.9.14

Fixes the following securoty issues:

- CVE-2017-8819: In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before
  0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before
  0.3.1.9, the replay-cache protection mechanism is ineffective for v2 onion
  services, aka TROVE-2017-009.  An attacker can send many INTRODUCE2 cells
  to trigger this issue.

- CVE-2017-8820: In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before
  0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before
  0.3.1.9, remote attackers can cause a denial of service (NULL pointer
  dereference and application crash) against directory authorities via a
  malformed descriptor, aka TROVE-2017-010.

- CVE-2017-8821: In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before
  0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before
  0.3.1.9, an attacker can cause a denial of service (application hang) via
  crafted PEM input that signifies a public key requiring a password, which
  triggers an attempt by the OpenSSL library to ask the user for the
  password, aka TROVE-2017-011.

- CVE-2017-8822: In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before
  0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before
  0.3.1.9, relays (that have incompletely downloaded descriptors) can pick
  themselves in a circuit path, leading to a degradation of anonymity, aka
  TROVE-2017-012.

- CVE-2017-8823: In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before
  0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before
  0.3.1.9, there is a use-after-free in onion service v2 during intro-point
  expiration because the expiring list is mismanaged in certain error cases,
  aka TROVE-2017-013.
