reflink: fix fragmentation tests to work on >4k block size filesystems

Browse Source 
For tests that only overwrite part of a file, only consider the number
of extents in the *rewritten* blocks when deciding if the FS
fragmentation performance is satisfactory.

(Also slip in a fix for xfs/127 so that it formats correctly when we
specify big blocksizes via MKFS_OPTIONS.)
