This fixes an issue where if certain tests ran concurrently, they would stomp on each other writing to a global directory. The problem is that
wrapped_clippy_driverwas writing to a global directory without any locking. The solution is to use the existing locking setup we have for supporting similar global tools.This doesn't often show up because the offending tests are usually separated enough alphabetically, but if they happen to run near each other, they would stomp on each other and corrupt the directory.
