selftests/bpf: Fix compilation error of bpf_iter_task_stack.c
BPF selftests show a compilation error as follows:
libbpf: invalid relo for 'entries' in special section 0xfff2; forgot to
initialize global var?..
Fix it by initializing 'entries' to zeros.
Fixes: c7568114bc56 ("selftests/bpf: Add bpf_iter test with bpf_get_task_stack()")
