Canonicalize some aspects of the folly/experimental/hazptr test

Summary:
[Folly] Canonicalize some aspects of the `folly/experimental/hazptr` test.

* Remove the custom `main()` and use the provided weak symbol, either from `folly/test/common/TestMain.cpp` or from `gtest` depending on the build.
* Extract some common setup/teardown (just debug logging in this case) to a test fixture.
