 In helping to debug https://trac.torproject.org/projects/tor/ticket/25386
 I've found that an unfortunate case is being hit where `cargo test` is
 using rustc's copy of the asan runtime instead of the system's copy, which
 causes problems due to presumably version mismatches between them.

 The error looks like https://travis-ci.com/alexcrichton/tor/jobs/141409956
 and only starts to show up after
 https://trac.torproject.org/projects/tor/ticket/27273 and
 https://trac.torproject.org/projects/tor/ticket/27272 are fixed.

 AFAIK the only "fix" for this is to basically just delete the sanitizer
 runtimes in the Rust sysroot as they're not used anyway, but I'll try to
 keep thinking and see if there's a better solution!
