fa7bef2e80 univalue: Remove unused and confusing set*() return value (MacroFake)

Pull request description:

  The value is:

  * currently unused, and useless without `[[nodiscard]]`
  * confusing, because it is always `true`, unless a num-string is set

  Instead of adding `[[nodiscard]]`, throw when setting is not possible.
