Fix quota(1) output.

- Fix calculation of 1024-byte sized blocks from disk blocks shown when -h
option isn't specified. It was broken with quota64 integration.
- In prthumanval(): limit the size of a buffer passed to humanize_number()
to a width of 5 bytes but allow a shorter length if requested. That's what
users expect.
