Includes extra file with possible custom firewall rules.

This way users can add their own rules by hand or maybe later with
a gui tool without fearing that their changes will be overwritten
by future updates of the nftable or a TridentOS package.
This extra file must still be included in the installer.

The pre-built examples file should also be renamed to custom-input.conf.sample.
Any file listed in this dir will automatically get replaced by the package every time it is installed/updated, so in order to preserve user modifications, it is better to label the package as an example or sample file, and have the user copy it before making changes.

I have to check if nft still starts if the file is renamed to *.sample
