Fix stack overflow in ZipArchiveIOSystem::MapArchive

The function allocates a filename buffer of 256, and copies the filename
extracted from the zip file into it. However, a filename might be larger
than 256 characters, in which case the function would write out of bounds.

This commit skips any file whose name is larger than 256 to avoid the
overflow.
