THRIFT-4845: Stop ignoring small timeouts

Client: php

CURLOPT_TIMEOUT requires a long [0], so it seems that small values
like 0.2 are being rounded to 0, resulting in a lack of any timeout.

This change uses CURLOPT_TIMEOUT_MS, which the PHP documentation
says was "added in cURL 7.16.2. Available since PHP 5.2.3."
