rust: Ensure unwind tables are generated
Currently, we are depending on a platform default in rustc's
android_base module to keep unwind tables generated. That default was
configured specifically to change the behavior for Firefox profiling
purposes prior to the existence of the override flag. As a result,
there's no structural reason the default will remain as is.
