rpminspect: Disable the unicode inspection

rpminspect reported:

    A forbidden code point, 0x202E, was found in the idna-3.9/tests/IdnaTestV2.txt

The file is fine. It's tests.

Note that ideally, we would only exclude test data, somehow like this:

    unicode:
        exclude: .*/tests/.*

However, it does not work (at least on Zuul CI).

(cherry picked from Fedora commit 96c5118ad6042153c6a45d5a8d670c97ee31cdb4)
