[HttpKernel] Fix call to Memcached::set() in MemcachedProfilerStorage

The existing code seems to have been copied from MemcacheProfilerStorage. Memcache::set() includes a $flag argument, but Memcached::set() omits that. See:

 * http://php.net/manual/en/memcached.set.php
 * http://php.net/manual/en/memcache.set.php

I assume Travis-CI didn't catch the MemcachedProfilerStorageTest failures because those tests are skipped: http://travis-ci.org/#!/symfony/symfony/jobs/678889/L104
