test: slightly reduce the performance/memory overhead for wrapped binaries

Browse Source 
Let's drop the quarantine that ASan uses for use-after-free detection,
as it's pointless in wrapped binaries and can consume up to 256 MiB of
memory (with the default configuration). Also, don't keep any stack
traces for allocations & deallocations, which should (slightly) help
with both memory & performance overhead.
