[8u] RFR 8240295: hs_err elapsed time in seconds is not accurate enough

[Zhengyu Gu]

I would like to backport this patch to 11u for parity with Oracle 8u271.

The original patch does not apply cleanly.

There is one conflict, where 8u (unpatched) misses leading space on 
following message:

st->print_cr(" elapsed time: %d seconds (%dd %dh %dm %ds)", eltime, 
eldays, elhours, elmins, elsecs);

Thanks,
