build script: Fix message on failed download (fixes #456) (#457)

Message displayed when file download fails, shows wrong information
about maximum number of attempts. Hardcoded value of '3' is shown,
but in reality there is up to six attempts (when subsequent downloads
keep failing).
Fix it by using correct value.
