[LTP] [PATCH] syscalls/copy_file_range02: use .needs_tmpdir and MAX_LEN

[Yang Xu]

Since commit bc514b22, we have removed EXDEV test. all_filesystem
,mount_device and mntpoint make no sense. Remove it and use tmpdir.

As man-page said, when we plan to write at a position past the maximum
allowed offset, it will return EFBIG. So we should USE MAX_LEN as pos
instead of MAX_OFF.
