Description of changes:

New version of libloading requires MSRV 1.71, which breaks the CI because out current MSRV is 1.63:

error: package libloading v0.8.9 cannot be built because it requires rustc 1.71.0 or newer, while the currently active rustc version is 1.63.0

Link to one of the failing builds: https://github.com/aws/s2n-tls/actions/runs/17929332729/job/50983002378?pr=5484
This CR pins its version to previous version 0.8.8.

libloading is a transitive dependency of bindgen. I ran cargo tree --invert libloading from /s2n-tls/bindings/rust/extended/generate:

libloading v0.8.9
├── clang-sys v1.8.1
│   └── bindgen v0.65.1
│       └── generate v0.1.0 (/home/ubuntu/s2n-tls/bindings/rust/extended/generate)
└── generate v0.1.0 (/home/ubuntu/s2n-tls/bindings/rust/extended/generate)

Call-outs:

I added this pin to our tracking issue: #4395

The performance regression test is failing, but this is expected. The performance regression test switches to mainline and generate the binding (which is broken and what the PR is addressing), so the failure is coming from main branch and not the branch from this PR

Testing:

Tests are now passing
