Add a denylist file for tests that should be skipped when built with
userspace ASAN:
$ make ... SAN_CFLAGS="-fsanitize=address -fno-omit-frame-pointer"
Skip the following tests:
- *arena*: userspace ASAN does not understand BPF arena maps and gets
confused particularly when map_extra is non-zero
- non-zero map_extra leads to mmap with MAP_FIXED, and ASAN treats
this as an unknown memory region
- task_local_data: ASAN complains about "incorrect" aligned_alloc()
usage, but it's intentional in the test
- uprobe_multi_test: very slow with ASAN enabled
