roles/common: Update list of abusive IP addresses

This comes from the AbuseIPDB with a confidence level of 95%. I use
the following command to download and sort the IPs:

$ curl -G https://api.abuseipdb.com/api/v2/blacklist -d confidenceMinimum=95 -H "Key: $ABUSEIPDB_API_KEY" -H "Accept: text/plain" | sort | sed -e '/:/w /tmp/ipv6.txt' -e '/:/d' > /tmp/ipv4.txt

I manually add the XML formatting to each file and run them through
tidy.
