  Log:
    [ruby/etc] Remove taint support
    
    Ruby 2.7 deprecates taint and it no longer has an effect.
    The lack of taint support should not cause a problem in
    previous Ruby versions.
    
    Still untaint the tmpdir object on Ruby <2.7, as returning
    a tainted string there could cause problems.
