With inspiration from @KevinBrolly, this patch uses the stack image SQLite3 package but also still providing the dev headers and binary that users may still be using today. The benefit is that we won't need to rebuild all the python binaries for this to take affect. We can just stop shipping SQLite3 from future binaries. In addition, we don't need to worry about what version and when to update SQLite3 and maintaining the packages ourselves. This also includes updates to Python 2.7.15 and Python 3.6.6 so they can rebuilt with the stack image dev headers instead of building our own vendored SQLite3.
