"ignore" does not work with relative paths that don't start with a wildcard glob

[FFdhorkin]

Describe the bug
jscpd does not ignore paths that start with a relative path (as opposed to wildcard glob). Absolute paths work fine.

For example, with the following .jscpd.json:

    "ignore": [
        "patches/**"
    ],
    "reporters": [
        "console",
        "html"
    ],
    "output": "./jscpdReport",
    "gitignore": true
}

The patches folder does not get ignored. Changing "patches/**" to "./patches/**" does not work, either.

However, changing "patches/**" to "**/patches/**" ignores the root patches folder, but carries the risk of ignoring a subfolder with the same name that shouldn't be ignored.

An absolute path works, but is non-portable: /home/username/repos/reponame/patches

To Reproduce
Steps to reproduce the behavior:

1. Have code in a subfolder that has a . prefix
2. manually add it to the ignore section of your config, using the path from project root
3. run jscpd
4. folder from step 1 is not ignored

Expected behavior
A path that is in the ignore should follow filesystem rules.

• /foo/** should ignore anything insides the system root "foo" folder.
• foo/** and ./foo/** should ignore anything inside the "foo" folder at the project root
