The nixspam spam-sources list was decommisioned in January and now

returns false positives in an attempt to encourage users to deconfigure
it. As this was the only list in the default spamd.conf, and the linked
wikipedia page that used to show other lists was removed in April 2024,
the default spamd.conf doesn't really seem useful any more, so remove it.
