Replace syscall.Syscall6, Syscall9, Syscall12, and Syscall15 with syscall.SyscallN for Go 1.18+. This simplifies system calls by allowing the exact number of arguments needed, eliminating zero padding and reducing potential errors. Updated TestSyscallXGeneration to TestSyscallNGeneration to verify correct SyscallN generation for different argument counts.
