strnstr should not treat the ending '\0' of s2 as a matching character,
otherwise the parameter 'len' will be meaningless, for example:
1. bpf_strnstr("openat", "open", 4) = -ENOENT
2. bpf_strnstr("openat", "open", 5) = 0
This patch makes (1) return 0, indicating a successful match.

Add two tests for bpf_strnstr():
bpf_strnstr("", "", 0) = 0
bpf_strnstr("hello world", "hello", 5) = 0
