Specific configurations for files that need no EOF

Pre-commit by default adds a single `\n` EOF to all files, but we have some tests that make sure that isn't done by Copier itself.

This specific behavior is committed separately to keep track of it. I'm adding an exclusion filter for files named `whatever.noeof.suffix`, and those are skipped by the `end-of-file-fixer` hook.

Also tests had to be changed accordingly. Nothing too special.
