bitbake: toaster/contrib: adding TTS squashed patch

In order to move the Toaster Test System in Toaster itself, we create a contrib directory. The TTS is added as a squashed patch with no history. It contains code contributed by Ke Zou <ke.zou@windriver.com>. (Bitbake rev: 7d24fea2b5dcaac6add738b6fb4700d698824286) Signed-off-by: Alexandru DAMIAN <alexandru.damian@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
