export/fuse: Pass default_permissions for mount
We do not do any permission checks in fuse_open(), so let the kernel do
them. We already let fuse_getattr() report the proper UNIX permissions,
so this should work the way we want.
This causes a change in 308's reference output, because now opening a
non-writable export with O_RDWR fails already, instead of only actually
attempting to write to it. (That is an improvement.)
