Incorrect Trailing Slash in ArEntry.Name for files in Debian Packages

When unpacking contents from a Debian package using` ArReader` and `ArEntry`, I encountered an error where the name (`ArEntry.Name`) of a `_gpgorigin` file contained a trailing slash. Specifically, when a Debian package includes a `_gpgorigin` file, `ArEntry.Name` is set to _`gpgorigin/`. The trailing slash is incorrect as `_gpgorigin` is a file, not a directory.

Updated the name to reflect that this happens with multiple files, not just `_gpgorigin`
