Now that we use cargo-llvm-cov, `exclude_path` should be a regular
expression, since we are using `--ignore-filename-regex` option:
--ignore-filename-regex <PATTERN>
Skip source code files with file paths that match the given
regular expression
To prevent users from separating multiple files with commas,
let's update the `exclude_path` description in the README and in
the examples.
