Fixed checksum upload validation when compressing LHE files

Script only gets the checksum of the files being added to EOS.
When compressing LHE files with the previous behavior, the script added a checksum for both the original .lhe file and the compressed .lhe.xz. Therefore, it would not compare the correct checksum to the file in EOS and and always produce a warning if the compression option was used.
