Filesystem API: Free the archive in _unzip_file_ziparchive().
There are several early returns in `_unzip_file_ziparchive()` which don't close the archive prior to returning.
As this function is used in installation and upgrade processes which are memory-intensive, this calls `ZipArchive::close()` to free the archive prior to each early return. This excludes the first return which is a result of a failure to open the archive, which is [https://github.com/nih-at/libzip/blob/main/lib/zip_open.c#L62-L73 freed internally] when the failure occurs.
