switch UNICODE_BETA to NO (one more try, first try didn't work)

    Unicode version 12.1.0 was officially released on May 7th, 2019.
    There were no changes at all from the "real" beta
    published shortly after the new era name "Reiwa" was announced.
    So we can switch UNICODE_BETA back to NO.

    common.mk: switch UNICODE_BETA back to NO
    tool/downloader.rb: add additional conditions to avoid an error
                        when moving from beta to final
