Replaced DNS_ALL with DNS_ANY as many servers hang on DNS_ALL
Replaced DNS_ALL with DNS_ANY as many servers hang on DNS_ALL

Hi,

After some investigation we've found that `DNS_ALL` on many systems do not work reliably, e.g. 2 demo services:

- https://odin2.stormcreative.co.uk/test.php (Linode)
- https://odin.stormcreative.co.uk/test.php (Digital Ocean)

You can see that `DNS_ANY` works but `DNS_ALL` errors.

The code used is:

```php
<?php
var_dump(dns_get_record('google.com', DNS_ANY));
var_dump(dns_get_record('google.com', DNS_ALL));
```

Replacing the above code causes the error to resolve
