selftests/bpf: Add update_elem failure test for task storage uptr
This patch test the following failures in syscall update_elem
1. The first update_elem(BPF_F_LOCK) should be EOPNOTSUPP. syscall.c takes
care of unpinning the uptr.
2. The second update_elem(BPF_EXIST) fails. syscall.c takes care of
unpinning the uptr.
3. The forth update_elem(BPF_NOEXIST) fails. bpf_local_storage_update
takes care of unpinning the uptr.
