build: use debug = "line-tables-only"

[morrisonlevi]

What does this PR do?

Switches from debug = 1 to debug = "line-tables-only".

Motivation

Was looking to try and shrink the builds for PHP (and libdatadog by extension) and noticed that since we're on Rust 1.71 now, we can make this small change.

Additional Notes

For more information about 1 vs line-tables-only, see: https://blog.rust-lang.org/2023/06/01/Rust-1.70.0.html#named-levels-of-debug-information.

How to test the change?

Everything should be the same.

The GitLab failure was cryptic. Rerunning the job, but I don't expect it to be an issue.

Nice catch!
