Do not automatically add "update" permission to shared mounts

In the past it seems the update permission was needed to be able to
rename shared mounts, but it doesn't seem to be the case any more.

Removing the "update" permission that used to be added automatically
fixes the read-only permission check when trying to overwrite a
read-only file over WebDAV.
