The bpf-nf selftests play various games with aliased types such that folks with CONFIG_NF_CONNTRACK=m/n configs can still build the selftests. See commits:
1058b6a78db2 ("selftests/bpf: Do not fail build if CONFIG_NF_CONNTRACK=m/n") 92afc5329a5b ("selftests/bpf: Fix build errors if CONFIG_NF_CONNTRACK=m")
Thus, it is simpler if these selftests opt out of using generated kfunc prototypes. The preprocessor macro this commit uses will be introduced in the final commit.
