selftests/bpf: Use sockaddr_storage instead of sa46 in select_reuseport test

The select_reuseport selftest uses a custom sa46 union to represent
IPv4 and IPv6 addresses. This custom wrapper requires extra manual
handling for address family and field extraction.

Replace sa46 with sockaddr_storage and update the helper functions to
operate on native socket structures. This simplifies the code and
removes unnecessary custom address-handling logic. No functional
changes intended.
