fix ASAN stl_tests:stl_vector_test

Summary:
folly/test/stl_tests/StlVectorTest.cpp was too slow under
mode/dev-asan, resulting in timeouts, and the relinquish test allocated
with malloc and freed with operator delete.  This diff reduces the vector
size for testing under ASAN, and fixes the allocation mismatch.
