app/fuzz: disable detect_leaks during fuzzer runtime



Detecting leaks while fuzzing cause asan to report incorrect memory
leaks, this behavior is cause by asan being disable for dpdk so every
memory that is allocated on heap and then store on hugepages is
reported as leaking even if there are correctly freed at the end.

This is a temporary solution until asan is enabled in dpdk
