fix(config): restore PHP (int) cast for ttl and timeout values

PHP's Config::get() applies an (int) cast to cache-files-ttl, cache-ttl,
and the process-timeout env override (Config.php:326,367,398), so string
values like '99999999' become integers. The strict PhpMixed::as_int
returned None for strings, collapsing them to 0. Use the intval shim,
which implements the PHP cast, and un-ignore
test_cache_garbage_collection_is_called which this had blocked.
