* RzBin/ELF: avoid the creation of useless flags at 0 Use UT64_MAX as an error value for addresses like symbols, imports, sections, etc., and do not create flags for those because they are not meaningful. This is useful for imports that do not have an address in the virtual/file space and for non-alloc sections (e.g. .comment).
