af-alg: Remove plugin for deprecated AF_ALG interface

The 7.2 kernel has officially deprecated the interface and it will soon
be removed (support for hardware crypto offload has already been removed).

Also removed the corresponding test scenarios.

The roadwarrior <b>carol</b> and the gateway <b>moon</b> use the <b>Crypto API</b>
of the Linux kernel via the <b>af_alg</b> userland interface for all symmetric
encryption and hash functions whereas roadwarrior <b>dave</b> uses <b>openssl</b>
as the default <b>strongSwan</b> cryptographical plugin.
<p>
The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each
to gateway <b>moon</b>. The authentication is based on <b>X.509 certificates</b>.
Upon the successful establishment of the IPsec tunnel automatically iptables-based
firewall rules are inserted which let pass the tunneled traffic.
In order to test both tunnel and firewall, both <b>carol</b> and <b>dave</b> ping
the client <b>alice</b> behind the gateway <b>moon</b>.
