91274ca535 bpf, sockmap: Update selftests to use skb_adjust_room 
Instead of working around TLS headers in sockmap selftests use the
new skb_adjust_room helper. This allows us to avoid special casing
the receive side to skip headers.

463bac5f1c bpf, selftests: Add test for ktls with skb bpf ingress policy 
This adds a test for bpf ingress policy. To ensure data writes happen
as expected with extra TLS headers we run these tests with data
verification enabled by default. This will test receive packets have
"PASS" stamped into the front of the payload.

d79a32129b bpf: Selftests, remove prints from sockmap tests 
The prints in the test_sockmap programs were only useful when we
didn't have enough control over test infrastructure to know from
user program what was being pushed into kernel side.

Now that we have or will shortly have better test controls lets
remove the printers. This means we can remove half the programs
and cleanup bpf side.
