Disable lsan.test_asyncify_during_exit. NFC

This test leaks allocates the asyncify stack during the exit handlers and
its never freed.

Interestingly enough this leak was not caught prior to #14280.
I did some investigation and found that prior to #14280 this
chunk was bring detected a reachable via the conservative stack
scan here:

 https://github.com/emscripten-core/emscripten/blob/98a8cbf5032f8d369be636a59180a59f1eb8833f/system/lib/compiler-rt/lib/lsan/lsan_common_emscripten.cpp#L141-L153

If I comment out this stack scan then this leak will be
detected even before #14280

Also, add `--profiling` to asan and lsan builds to make
error reports more useful.

See #14360
