fix(nfs): move fsid=N inside client parentheses in /etc/exports

exportfs parses 'path host(flags) fsid=N' as a separate fsid= token
without host or options, causing 'No options for path fsid=N' errors.
The correct format puts fsid=N inside the host parentheses:
  /path host(flags,fsid=N)

Changes:
- clientFlags(c, fsid) now appends fsid=N at the end
- buildExportFlags(e, fsid) same
- buildExportLine removed buildExportSuffix call; fsid is now per-client
- Removed now-unused buildExportSuffix function
