Due to changes in the file zip terminology from Linux.zip to Linux-x64.zip, as a result of the change in file naming convention, the COIN_TGZ had to be remade.
With the current implementation, the script will search for and support both file types, whether they already have a release with the latest deterministic build (Linux-x64.zip) or still the normal one (Linux.zip).
Take in consideration that the detreministic builds going to be the standard for DMY blockchains, however with this update in the multinode script there is no need to further updates regarding this point.
