[PATCH v2 04/13] tools/nolibc: add missing nanoseconds support for __NR_statx

[Zhangjin Wu]

Commit a89c937d781a ("tools/nolibc: support nanoseconds in stat()")
added nanoseconds for stat() but missed the statx case, this adds it.

The stx_atime, stx_mtime, stx_ctime are in type of 'struct
statx_timestamp', which is incompatible with 'struct timespec', should
convert explicitly.

    /* include/uapi/linux/stat.h */

    struct statx_timestamp {
    	__s64	tv_sec;
    	__u32	tv_nsec;
    	__s32	__reserved;
    };

    /* include/uapi/linux/time_types.h */
    struct __kernel_timespec {
    	__kernel_time64_t       tv_sec;                 /* seconds */
    	long long               tv_nsec;                /* nanoseconds */
    };

    /* tools/include/nolibc/types.h */
    #define timespec __kernel_timespec

Without this patch, the stat_timestamps test case would fail on rv32.
