PR Description

Enabled the lua filter plugin which was previously disabled because it pulled in a copy of the luajit library, which it wanted to install.
fluent/fluent-bit#7286 (in 3.1.5) makes it possible to use the system luajit library instead of the vendored version.
With this change, the lua filter plugin can be built with the system luajit library.

Also, according to https://fluentbit.io/announcements/older-versions/, the 3.0 line went EOL on Sep 11 2024.

• Updated fluent-bit to upstream 3.1.9. Enabled use of lua filter plugin with system luajit library.
• Fixes Enable lua filter for fluent-bit #10675

Regression Risk

To the best of your knowledge, where might potential problems/regressions arise?

According to Upgrade Notes | Fluent Bit: Official Manual, there have not been any breaking changes for a long time. None of the release notes between 3.0.6 and 3.1.9 mention any breaking changes either.

Does this affect the toolchain?

NO
