selftests/bpf: Move kfunc exports to bpf_testmod/bpf_testmod_kfunc.h
Move all kfunc exports into separate bpf_testmod_kfunc.h header file
and include it in tests that need it.
We will move all test kfuncs into bpf_testmod in following change,
so it's convenient to have declarations in single place.
The bpf_testmod_kfunc.h is included by both bpf_testmod and bpf
programs that use test kfuncs.
As suggested by David, the bpf_testmod_kfunc.h includes vmlinux.h
and bpf/bpf_helpers.h for bpf programs build, so the declarations
have proper __ksym attribute and we can resolve all the structs.
Note in kfunc_call_test_subprog.c we can no longer use the sk_state
define from bpf_tcp_helpers.h (because it clashed with vmlinux.h)
and we need to address __sk_common.skc_state field directly.
