Bug description:
  [Impact]
  unzip rejects Microsoft OneDrive zip files. See the detailed explanation here:

  https://www.bitsgalore.org/2020/03/11/does-microsoft-onedrive-export-
  large-ZIP-files-that-are-corrupt

  tl;dr;
  Microsoft mishandles the "Total number of disks" field when using the ZIP64 extension. It should start at 1, they use 0, which isn't a valid value. Unzip doesn't properly handle the invalid value.

  [Test Plan]
  - Download the test zip file from comment #1.
  - unzip should extract it without issue (it contains a test.txt text file)
  - if unzip fails, it will spew out a weird error message like the following:

  $ unzip test.zip
  Archive:  test.zip
  error [test.zip]:  missing 4294967098 bytes in zipfile
    (attempting to process anyway)
  error [test.zip]:  start of central directory not found;
    zipfile corrupt.
    (please check that you have transferred or created the zipfile in the
    appropriate BINARY mode and that you have compiled UnZip properly)

  [Where problems could occur]
  This simple patch just accepts 0 as a valid total number of disks. I suppose if it was wrong it would mishandle multi-disk archives, though multi-disk archives should have a good value in that field.
