mount: Add "no-default-permissions" option

This option restores the previous behavior of `mount` by disabling the "DefaultPermissions" FUSE option. This allows any user that can access the mountpoint to read any file from the snapshot. Normal FUSE rules apply, so `allow-root` or `allow-other` can be used to allow users besides the mounting user to access these files.
