bpo-31525: Increase minimum sqlite version number check

[LordAro]

setup.py checks for a minimum version of sqlite when building the _sqlite3 extension, but it checks for 3.0.8, whereas the extension makes use of sqlite3_prepare_v2, which was introduced in 3.3.9 - https://sqlite.org/releaselog/3_3_9.html

This PR just bumps the required version number, so that possible failures are detected earlier and are more clear

(I know it's still absolutely ancient, but RHEL5...)

Hello, and thanks for your contribution!

I'm a bot set up to make sure that the project can legally accept your contribution by verifying you have signed the PSF contributor agreement (CLA).

Unfortunately we couldn't find an account corresponding to your GitHub username on bugs.python.org (b.p.o) to verify you have signed the CLA (this might be simply due to a missing "GitHub Name" entry in your b.p.o account settings). This is necessary for legal reasons before we can look at your contribution. Please follow the steps outlined in the CPython devguide to rectify this issue.

You can check yourself to see if the CLA has been received.

Thanks again for your contribution, we look forward to reviewing it!

CLA signed now. I don't think an issue number or a news entry is necessary...

CLA signed now. I don't think an issue number

There is https://bugs.python.org/issue31525 which would be appropriate

I thought we've already updated setup.py, but apparently we weren't... Good catch!
