Fix ZipDecompressor windows 0x80 (file attribute normal) (bazelbuild#…

…15907)

Fixes bazelbuild#9236. On a rare occasion a zip file contains files with the 0x80 attribute.

From https://docs.microsoft.com/en-us/windows/win32/fileio/file-attribute-constants
A file that does not have other attributes set. This attribute is valid only when used alone.

Closes bazelbuild#15260.
