Update accessibility watchlists.

Update accessibility watchlists.

Subscribe nektar@chromium.org and je_julie.kim@samsung.com, and simplify
the file paths to just catch any file that includes one of these keywords
in the path rather than trying to enumerate every path:

accessibility, braille, chromevox, iaccessible2, isimpledom, liblouis

Let me know if I missed any keywords! In particular, are there any
accessibility-related files in the code tree that don't contain one of these
keywords as a substring?  (This doesn't count Blink.)
