Hard coded reflink offset/length numbers are not working well on 64K page
size arch like ppc64le, reporting:
+XFS_IOC_CLONE_RANGE: Invalid argument
Because they are not aligned with the current PAGE_SIZE.
Translate original numbers into multiples of PAGE_SIZE. Then we're writing
different testfiles with different md5sums when PAGE_SIZE is different.
So we need to link different output file based on the current PAGE_SIZE.
This testcase is covering a btrfs regression which has been fixed in
v4.18. I tried to reproduce it on 4.17 kernel but failed with and
without this patch.
