selftests/bpf: Add csum helpers
Checksum helpers will be used to calculate pseudo-header checksum in
AF_XDP metadata selftests.
The helpers are mirroring existing kernel ones:
- csum_tcpudp_magic : IPv4 pseudo header csum
- csum_ipv6_magic : IPv6 pseudo header csum
- csum_fold : fold csum and do one's complement
