[ANNOUNCEMENT] Kselftest wiki updated

[Shuah Khan]

All,

Updating Kselftest wiki and providing links to overview and how-to documents
has been on my list of things to do for a while.

It is now updated with the current status and links to documents. I am planning
to write a detailed how-to blog/article.
