PHPT tests treat line endings inconsistently

[vclayton]

Similar to #1115, PHPT tests can fail if the line endings of the EXPECT/EXPECTF section don't match the line endings in the test output. The behavior is also inconsistent with run-tests.php and PEAR_RunTest.

In run-tests.php, the all output is run through preg_replace("/\r\n/", "\n", trim($out));
The expected output is processed the same way, for both EXPECT and EXPECTF sections.
