selftests/bpf: Add 6-argument syscall tracing test Turns out splice() is one of the syscalls that's using current maximum number of arguments (six). This is perfect for testing, so extend bpf_syscall_macro selftest to also trace splice() syscall, using BPF_KSYSCALL() macro. This makes sure all the syscall argument register definitions are correct.
