selftests/bpf: Ensure cgroup/connect{4,6} programs can bind unpriv ICMP ping
This tests that when an unprivileged ICMP ping socket connects,
the hooks are actually invoked. We also ensure that if the hook does
not call bpf_bind(), the bound address is unmodified, and if the
hook calls bpf_bind(), the bound address is exactly what we provided
to the helper.
A new netns is used to enable ping_group_range in the test without
affecting ouside of the test, because by default, not even root is
permitted to use unprivileged ICMP ping...
