xfs: fallocate free space into a filedefrag-freespace_2022-10-14

Add a new fallocate mode to map free physical space into a file, at the
same file offset as if the file were a sparse image of the physical
device backing the filesystem.  The intent here is to use this to
prototype a free space defragmentation tool.
