    rust: abort on panic in all profiles
    
    Until https://github.com/rust-lang/rust/issues/52652 is fixed,
    unwinding on panic is potentially unsound in a mixed C/Rust codebase.
    
    The codebase is supposed to be panic-free already, but just to be safe.
    
    This started mattering at commit d1820c1516a31a149fc51a9e5126bf899e4c4e08.
    
    Fixes #27199; bugfix on tor-0.3.3.1-alpha.
