humanize_number(3): fix math edge case in rounding large numbers

Fix for remainder overflow, when in rare cases adding remainder to divider
exceeded 1 and turned the total to 1000 in final formatting, taking up
the space for the unit character.

The fix continues the division of the original number if the above case
happens -- added the appropriate check to the for loop performing
the division. This lowers the value shown, to make it fit into the buffer
space provided (1.0M for 4+1 character buffer, as used by ls).

Add test case for the reported bug and extend test program to support
providing buffer length (ls -lh uses 5, tests hard-coded 4).

For numbers greater than 999 using buffer length of 4 and less can cause
rounding errors.
When using
.Dv HN_IEC_PREFIXES
the same error occurs for buffer length of 5 or less.
