Christian Ehrig d9688f898c selftests/bpf: Test FOU kfuncs for externally controlled ipip devices
Add tests for FOU and GUE encapsulation via the bpf_skb_{set,get}_fou_encap
kfuncs, using ipip devices in collect-metadata mode.

These tests make sure that we can successfully set and obtain FOU and GUE
encap parameters using ingress / egress BPF tc-hooks.
