nixos/networkd: allow configuring AckFilter for CAKE qdisc

Browse Source 
The CAKE section for systemd.network units allows configuring whether or
not redundant ACKs should be dropped. This option corresponds to the
respective tc-cake(8) params "ack-filter", "ack-filter-aggressive" or
"no-ack-filter".

Add support for these values in the `cakeConfig` module so that users
can configure it.
