fac22fd36b log: Remove GetAdjustedTime from IBD header progress estimation (MarcoFalke)

Pull request description:

  This is a "refactor" that shouldn't change behaviour, because the two times are most likely equal. A minimum of 5 outbound peers are needed to adjust the time. And if the time is adjusted, it will be by at most 70 minutes (`DEFAULT_MAX_TIME_ADJUSTMENT`). Thus, the progress estimate should differ by at most 7 blocks.
