ipblocklist-functions.pl: Allow downloading empty blocklists

Some blocklist providers does serve blocklists for current events or
with very limited updates. Therefore there is a chance such a blocklist
could be empty for a certain time.

This patch allows to replace an existing filled blocklist by an empty
one and vice versa.

Fixes #13804.
