Subject: selftests/bpf: Pass sanitizer flags to linker through LDFLAGS
Patch-mainline: v5.17-rc1
Git-commit: 2a2cb45b727b7a1041f3d3d93414b774e66454bb
References: jsc#PED-1368

When adding -fsanitize=address to SAN_CFLAGS, it has to be passed both
to compiler through CFLAGS as well as linker through LDFLAGS. Add
SAN_CFLAGS into LDFLAGS to allow building selftests with ASAN.
