Fix random failure of retry_allocator_test

The original implementation makes 4 threads to allocate the same memory, each thread sleep 40ms, and the retry time is 3*(40+10)ms.

It may result in failure if a thread cannot finish in 10ms, which can be caused by os scheduling.

This PR increases the retry time.
