attach_probe test fails, because it cannot install a kprobe on a
non-existent sys_nanosleep symbol.
Use the correct symbol name for the nanosleep syscall on 64-bit s390.
Don't bother adding one for 31-bit mode, since tests are compiled only
in 64-bit mode.
Fixes: 1e8611bbdfc9 ("selftests/bpf: add kprobe/uprobe selftests")
