The global variable `default_DSO_meth` was potentially set multiple times by different threads. It turns out that it could only be set to a single value so the race is harmless but still better avoided. The fix here simply removes the global and accesses the value it was set to via the `DSO_METHOD_openssl()` call. Problem discovered via openssl#16970, but this does not resolve that issue because there are other concerns.
