fix: enable bindgen feature of aws-lc-rs

Since 1.6.1 aws-lc-sys no longer automatically generates its bindings,
instead requiring you to enable the `bindgen` feature if you want to.

This fixes the CI error

```
thread 'main' panicked at
[...]/aws-lc-sys-0.13.0/builder/main.rs:286:5:
E     aws-lc-sys build failed. Please enable the 'bindgen' feature on
aws-lc-rs or aws-lc-sys
```
