The former whattime logic used to suppress that 'days'
output when the system had been up less than 24 hours.
But since the refactor for newlib, '0 days' was always
output under those conditions. So this commit restores
the former expected behavior of suppressing that item.
[ plus an erroneous calculation of uphours was fixed ]
[ and the clang warnings shown below were also fixed ]

Removed the printf_uptime, binaries can do printf easily enough.
sprint_uptime split into two as there wasn't a lot of common
code
sprint_uptime(): old style uptime line
sprint_uptime_short(): short new style "uptime -p"
Hertz_hack needed this, no sane system uses the code (I think)
so just assume 100 like we do in FreeBSD.
