AHM ASAN test adjustment

Summary:
The AHA-insert-race test case (a) does a LOT of iterations, and
(b) allocated and deallocates a lot of memory on each iteration.

The long iterations, by themselves, take 8s, and should be reduced.
Further, ASAN errors on these tests, since it needs to hold on to memory
for a bit of time and ends up OOMing.

Test Plan:
fbconfig -r 'folly' '--platform-all=gcc-4.8.1-glibc-2.17-fb' '--sanitize=address'
fbmake runtests Ahm.atomic_hash_array_insert_race
