sqlite: 3.16.2 -> 3.17.0

Firefox requires the latest sqlite to build:
```
checking for sqlite3 >= 3.17.0... Requested 'sqlite3 >= 3.17.0' but version of SQLite is 3.16.2
configure: error: Library requirements (sqlite3 >= 3.17.0) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
```
