git-archive --format=zip: add symlink support
Add symlink support to ZIP file creation, and a few tests. This implementation sets the "version made by" field (creator_version) to Unix for symlinks, only; regular files and directories are still marked as originating from FAT/VFAT/NTFS. Also set "external file attributes" (attr2) to 0 for regular files and 16 for directories (FAT attribute), and to the file mode for symlinks. We could always set the creator_version to Unix and include the mode, but then Info-ZIP unzip would set the mode of the extracted files to *exactly* the value stored in attr2. The FAT trick makes it apply the umask instead. Note: FAT has no executable bit, so this information is not stored in the ZIP file.
