If the length of a stored file is more than 2^32 and a data descriptor
is not being used then a ZIP64 extra is required in the file header to
store the uncompressed and compressed lengths.

The extended-timestap extra block changes between Local File Header and
Central Directory. We have to strip it out to avoid mis-filling during
zip2zip.

This was blindly copying the zip64 extra fields from the central
directory of the original zip file to the new one. The zip64 extra
fields depend on the contents of the header it's attached toa, and in
this case we were copying the zip64 file header offset from the central
directory entry into the destination local file header, which makes no
sense, especially since the offset changed in the new file.
So strip all zip64 extra entries, and we'll create them as necessary
when writing ou the new file.
