Bug 1270882 - Enable support for SQLite custom FTS3 tokenizers at run time.

Do not require that SQLite has been built with support for custom FTS3
tokenizers enabled by default. This allows to use system SQLite in
distributions which provide SQLite configured in this way (which is SQLite
upstream's default configuration due to security concerns).

Requires exposing the sqlite3_db_config symbol in bundled SQLite.

Disable no longer needed setting of SQLITE_ENABLE_FTS3_TOKENIZER macro in
bundled SQLite build.
