fix new/delete in sanitize-address test

Summary:
The use of `operator new` with sized `operator delete` in `folly/memory/test/SanitizeAddressTest.cpp` requires sized `operator delete`, which is not always available.

Delegation to the correct `operator delete` is wrapped in `folly::operator_new` and `folly::operator_delete`, so switch to these.
