iolib: fix different behavior in read function

$ lua
Lua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio
> file = "/tmp"
> fd, _, code = io.open(file, "r")
> _, _, ecode = fd:read(1)
> print(ecode)

gopher-lua throws an exception:
        read /tmp: is a directory
stack traceback:
        [G]: in function 'read'
        extra/wrapper.lua:17: in function 'exec'
        <string>:1: in main chunk
        [G]: ?

This patch results in behavior similar to the vanilla lua
implementation.

Closes #455
