nixos/taskserver: Rename .server options to .pki

After moving out the PKI-unrelated options, let's name this a bit more
appropriate, so we can finally get rid of the taskserver.server thing.

This also moves taskserver.caCert to taskserver.pki.caCert, because that
clearly belongs to the PKI options.
