Eduard Zingerman d9631d0d8c selftests/bpf: track tcp payload offset as scalar in xdp_synproxy
commit 977bc146d4 upstream.

This change prepares syncookie_{tc,xdp} for update in callbakcs
verification logic. To allow bpf_loop() verification converge when
multiple callback itreations are considered:
- track offset inside TCP payload explicitly, not as a part of the
  pointer;
- make sure that offset does not exceed MAX_PACKET_OFF enforced by
  verifier;
- make sure that offset is tracked as unbound scalar between
  iterations, otherwise verifier won't be able infer that bpf_loop
  callback reaches identical states.
