Bug description:When flag DROP_NEW_LINE is enabled, line read stops at null char

Description:
------------
When the flag DROP_NEW_LINE is enabled in SplFileObject classes, reading
a line (e.g. fgets()) stops at null char.

When the flag is disabled, the read operation works as intended.

Test script:
---------------
<?php

// string with a NULL char
$line = "Lorem ipsum \0 dolor sit amet";

$temp = new SplTempFileObject();
$temp->fwrite($line);

$temp->rewind();
$read = $temp->fgets();
echo 'SplFileObject::DROP_NEW_LINE flag -> disabled' . PHP_EOL;
var_dump(strcmp($line, $read), $read);

$temp->rewind();
$temp->setFlags(SplFileObject::DROP_NEW_LINE);
$read = $temp->fgets();
echo PHP_EOL . 'SplFileObject::DROP_NEW_LINE flag -> enabled' .
PHP_EOL;
var_dump(strcmp($line, $read), $read);
