Subject: [PATCH] fuse-overlayfs: ignore xattrs copy errors when not supported

it solves this error on copy_xattrs when the underlying file system is
overlay:

flistxattr(9, "security.selinux\0", 1048576) = 17
fgetxattr(9, "security.selinux", "system_u:object_r:container_file"..., 256) = 48
fsetxattr(10, "security.selinux", "system_u:object_r:container_file"..., 48, 0) = -1
