tor: update to 0.4.6.6.

Changes in version 0.4.6.6 - 2021-06-30
  Tor 0.4.6.6 makes several small fixes on 0.4.6.5, including one that
  allows Tor to build correctly on older versions of GCC. You should
  upgrade to this version if you were having trouble building Tor
  0.4.6.5; otherwise, there is probably no need.

  o Minor bugfixes (compilation):
    - Fix a compilation error when trying to build Tor with a compiler
      that does not support const variables in static initializers.
      Fixes bug 40410; bugfix on 0.4.6.5.
    - Suppress a strict-prototype warning when building with some
      versions of NSS. Fixes bug 40409; bugfix on 0.3.5.1-alpha.

  o Minor bugfixes (testing):
    - Enable the deterministic RNG for unit tests that covers the
      address set bloomfilter-based API's. Fixes bug 40419; bugfix
      on 0.3.3.2-alpha.
