Update kyua-testers to 0.3:

Experimental version released on August 8th, 2014.

* Made the testers set a "sanitized" value for the HOME environment
  variable where, for example, consecutive and trailing slashes have
  been cleared.  Mac OS X has a tendency to append a trailing slash to
  the value of TMPDIR, which can cause third-party tests to fail if they
  compare ${HOME} with $(pwd).

* Issues 85, 86, 90 and 92: Made the TAP parser more complete: mark test
  cases reported as TODO or SKIP as passed; handle skip plans; ignore
  lines that look like "ok" and "not ok" but aren't results; and handle
  test programs that report a pass but exit with a non-zero code.
