nwarchive: scope private xattrs under NetWare namespace

Move the mars_nwe NetWare-core archive/fileinfo xattr names from the flat org.mars-nwe namespace into an explicit org.mars-nwe.netware subnamespace.

The earlier xattr namespace cleanup intentionally removed the unreleased user.mars_nwe names and introduced Netatalk-style org.mars-nwe source-level keys.  Keeping archive and fileinfo at org.mars-nwe.archive and org.mars-nwe.fileinfo would make those NetWare server metadata records peers of AFP metadata instead of identifying their ownership.  The archive date/time/archiver and file create/creator/modifier records are NetWare-core file metadata, so place them under org.mars-nwe.netware.* while leaving AFP metadata under org.mars-nwe.afp.*.

No legacy fallback is added because the old names only existed in local test systems and have not been released.  The existing nwxattr wrapper still maps source-level org.mars-nwe.<domain>.* names to user.org.mars-nwe.<domain>.* on Linux, mirroring Netatalk's org.netatalk.* EA abstraction.

Tests: git diff --check

TODO: keep future nwbind/nwserv/AFP metadata in explicit org.mars-nwe.<domain>.* subnamespaces instead of adding new flat org.mars-nwe.* keys.
