Log Message:
Update devel/kyua to 0.13:

**Released on August 26th, 2016.**

* Fixed execution of test cases as an unprivileged user, at least under
  NetBSD 7.0.  Kyua-level failures were probably a regression introduced
  in Kyua 0.12, but the underlying may have existed for much longer:
  test cases might have previously failed for mysterious reasons when
  running under an unprivileged user.

* Issue #134: Fixed metadata test broken on 32-bit platforms.

* Issue #139: Added per-test case start/end timestamps to all reports.

* Issue #156: Fixed crashes due to the invalid handling of cleanup
  routine data and triggered by the reuse of PIDs in long-running Kyua
  instances.

* Issue #159: Fixed TAP parser to ignore case while matching `TODO` and
  `SKIP` directives, and to also recognize `Skipped`.

* Fixed potential crash due to a race condition in the unprogramming of
  timers to control test deadlines.
