Remove 50 KiB and 1 MiB downloads.

With the new partial downloads timestamps we can easily extract time-to-first-50-KiB and time-to-first-1-MiB numbers from the 5 MiB downloads. An analysis of past measurements showed that these numbers are comparable. By removing those smaller downloads we increase the total number of actually useful measurements. Total bandwidth consumption from this change increases from 14 to 140 kbps which still seems very reasonable. Implements #34023.

Remove 50 KiB and 1 MiB downloads.
