rec: Fix a few cases discoverd by tsan:

- The NegCache and MemRecursorCache destructors were not deadlock free
  when running from testrunner. The purpose of the code in the dts
  is also unclear, so delete them.

- quit-nicely uses a volatile sig_atomic_t, which is not thread-safe
  according to tsan. Replace by atomic.
