Add {de,at}.alhp.mirror.kescher.at (#25)

Hi, as shown on [the kescher.at mirrors page](https://mirror.kescher.at/#alhp), I am now hosting a mirror in both Germany and Austria.

Technically, there is also a DNS-level GeoIP subdomain at https://alhp.mirror.kescher.at, but as with the other two mirrors, I don't really put them anywhere, since mirror ranking tools are much better suited to finding an optimal mirror location.

The mirrors each have up to 2.5 Gbps of bandwidth, host rsync and https, and support both IPv4 and IPv6.
