utimensat_time64

change file timestamps with nanosecond precision

sys_utimensat(int dfd, const char *filename, struct __kernel_timespec *utimes, int flags)

register	value
`g1`	412, the syscall number
`o0`	int dfd
`o1`	const char *filename
`o2`	struct __kernel_timespec *utimes
`o3`	int flags
`o0`	the return value

Then run t 0x10 to enter the kernel.

Same syscall on other architectures
