macOS - '/System/Volumes/Data' DiskDevice path remapping

[kapitainsky]

Fixes https://github.com/pkolaczk/fclones/issues/158

On macOS APFS disk all users' data is mounted in '/System/Volumes/Data' but fused transparently using firmlinks and presented as part of the root filesystem. It requires remapping Data volume path for this DiskDevice to '/' in order for fclones correctly recognise device deduplicated files are on.
