bpo-30891: Fix importlib _find_and_load() race condition (#2646) (#2651)

* Rewrite importlib _get_module_lock(): it is now responsible to hold
  the imp lock directly.
* _find_and_load() now holds the module lock to check if name is in
  sys.modules to prevent a race condition
(cherry picked from commit 4f9a446f3fb42f800e73cd9414dd1eccb3ca4fa7)
