[PATCH bpf-next v2 2/2] selftests/bpf: Add IP_TRANSPARENT and IPV6_TRANSPARENT to setget_sockopt

[Shivaji Kant <shivajikant@google.com>]

Add test coverage for IP_TRANSPARENT and IPV6_TRANSPARENT socket options
in the setget_sockopt BPF selftest to verify bpf_setsockopt() and
bpf_getsockopt() helpers.
