WebSQL: Add LayoutTests for blocked SQLite FTS3 features.

Chrome patches SQLite to remove two features from the FTS3 extension. This CL adds LayoutTests verifying that the features are not available to WebSQL. The tests ensure that we won't accidentally expose the features as we shed our SQLite patches. Bug: 945204 Change-Id: I50364520c33bdfbbbc9b5521fcf6dff37d9fe419 Tested: Ran the blocked commands in a vanilla sqlite3 shell.
