fix: encodeTuple int32 panic

[linehk]

When using int32 type in tuple and Pack, error will occur:

panic: unencodable element at index 0 (1, type int32)

The following example can be reproduced:

package main

import (
    "github.com/apple/foundationdb/bindings/go/src/fdb"
    "github.com/apple/foundationdb/bindings/go/src/fdb/tuple"
)

func main() {
    fdb.MustAPIVersion(730)
    var i int32 = 1
    tuple.Tuple{i}.Pack()
}

This is because encodeTuple does not handle int32.

In the Go language, int and int32 are not the same type.

Fixed by adding support for int32.
