This series includes various fixes aiming to enable test_progs run
with userspace address sanitizer on BPF CI.

The first patch fixes the selftests/bpf/test_progs build with:

    SAN_CFLAGS="-fsanitize=address -fno-omit-frame-pointer"

The subsequent patches fix bugs reported by the address sanitizer on
attempt to run the tests.

---

v1->v2:
  - rebase on bpf (v1 was targeting bpf-next)
  - add ASAN flag handling in selftests/bpf/Makefile (Eduard)
  - don't override SIGSEGV handler in test_progs with ASAN (Eduard)
  - add error messages in detect_bpftool_path (Mykyta)
  - various nits (Eduard, Jiri, Mykyta, Alexis)

v1: https://lore.kernel.org/bpf/20260212011356.3266753-1-ihor.solodrai@linux.dev/
