Screen the .attribute directory on NetBSD
This directory holds the extended attribute backing store on FFSv1 filesystems. It should be ignored by glusterfs just like the .glusterfs directory. Fixes: #1361 Change-Id: Ia259be2af722a651473a312b5044b431c2b01b10 Type: Bug Signed-off-by: Emmanuel Dreyfus <manu@netbsd.org>
