KF_IMPLICIT_ARGS kfuncs have a BPF-call prototype and a real kernel
target prototype. Add a tracing selftest that attaches fentry and fexit
programs to bpf_kfunc_implicit_arg(), runs a syscall BPF program that
calls it, and checks that the tracing context exposes both the explicit
argument and the implicit prog aux pointer.
