Update Travis-CI

Moved `sqlite_vacuum_incr` and `sqlite_vtable` to module job.

* `sqlite_vacuum_incr` will only store the required auto vacuum information into the datbase page, and not peform an vacuum therefor this can be added easily to the module job.
- `sqlite_vtable` does not require an seperate job because user will include the tag in combination with others.
