dep: update packaged sqlite3 to 3.43.2

[flavorjones]

From the forum announcement:

SQLite version 3.43.2 is now available. Version 3.43.2 is a small patch
to version 3.43.1 and 3.43.0 that fixes some minor inaccuracies and also
addresses some problems in the build scripts. The changes probably do not
affect your projects, but you are welcomed to upgrade nevertheless.

Details from https://sqlite.org/releaselog/3_43_2.html

• Fix a couple of obscure UAF errors and an obscure memory leak.
• Omit the use of the sprintf() function from the standard library in the CLI, as this now generates warnings on some platforms.
• Avoid conversion of a double into unsigned long long integer, as some platforms do not do such conversions correctly.
