This was caused by a zip64 archive in the golang test suite.
Archive::Zip, and hence strip-nondeterminism, doesn't support zip64
archives.  Fortunately, zip64 archives are rare and the one in the
golang source doesn't contain any nondeterminism, so I've modified
strip-nondeterminism to just ignore zip64 archives.
