run-tests broken in HEAD

Hi!

Tried today to work on some tests and discovered that run-tests is not
binary-safe in php 6 - it can not process arbitrary outputs. Consider
this test:

--TEST--
Test
--FILE--
<?php

$a = b"\xD0";
var_dump($a);
--EXPECT--
string(1) ""

It should not pass - output string is wrong - but instead of failing
correctly, the run-tests script itself produces these errors:

TEST:N 1/2 [t0.phpt]
Warning: Could not convert binary string to Unicode string (converter
UTF-8 failed on bytes (0xD0) at offset 0) in /root/php6/run-tests.php on
line 952
PASS:N Test [t0.phpt]
TEST:U 2/2 [t0.phpt]
Warning: Could not convert binary string to Unicode string (converter
UTF-8 failed on bytes (0xD0) at offset 0) in /root/php6/run-tests.php on
line 952
PASS:U Test [t0.phpt]

I think this needs to be fixed.
