selftests/bpf: Add tests for {set|get} socket option from setsockopt BPF
Adding selftests for the newly added functionality to call bpf_setsockopt()
and bpf_getsockopt() from setsockopt BPF programs.
Test Details:
1. BPF Program
Checks for changes in IPV6_TCLASS(SOL_IPV6) via setsockopt
If the cca for the socket is not cubic do nothing
If the newly set value for IPV6_TCLASS is 45 (0x2d) (as per our use-case)
then change the cc from cubic to reno
2. User Space Program
Creates an AF_INET6 socket and set the cca for that to be "cubic"
Attach the program and set the IPV6_TCLASS to 0x2d using setsockopt
Verify the cca for the socket changed to reno
