Deduplicate NFS exports and remove client info

Fix NFS export display to show each export path only once instead of
once per client. Use HashMap to deduplicate by path and sort results
alphabetically. Remove IP addresses and client specifications from
display, showing only export paths with their options.

Prevents duplicate entries when a single export is shared with multiple
clients or networks.
