Subject: Disable over-eagerly MSOOXML detection

    Upstream commit FILE5_46-106-g8cef37b5 ("PR/0644: omajid: Recognize
    NuGet packages") enhanced the list of what files in the listing in a
    ZIP archive might be an MS OOXML file. The rationale is not clear,
    but under some circumstances this causes ZIP files to be
    mis-detected.

    Revert this part of the above commit for the time being.
