progress: adjust minimum thresholds for ETA to 10 seconds and 1 GiB of data

1% is a lot of data on a petabyte filesystem, and a long time to wait for an
ETA.

After 1 GiB we should have some idea of how fast we're reading the data.
Increase the time to 10 seconds to avoid a nonsense result just after a scan
starts.
