fix open bindings

Browse Source 
`open` specifies the `mode` argument as vararg (presumably to make it
optional). varargs actually have rules about casting, in this case the
rule that any integer arg of size <= 4 has to be casted to `i32` before
passing it.

Not doing that implicit cast makes the permissions wrong or not apply at
all.
