selftests/bpf: Temporarily disable linked list tests
The latest clang nightly as of writing crashes with the given test case
for BPF linked lists wherever global glock, ghead, glock2 are used,
hence comment out the parts that cause the crash, and prepare this commit
so that it can be reverted when the fix has been made. More context in [0].
