[tserver] disable KUDU-3486 behavior by default

This is a quick-and-dirty fix to mitigate KUDU-3638.

This patch isn't focusing on properly addressing the issues that
KUDU-3486 has introduced apart from fixing the obvious bug of missing
updates of the Heartbeater::Thread::last_tombstoned_report_time_ field.
Also, with this patch, the functionality introduced with KUDU-3486
is now disabled by default.  To re-enable it back, customize the setting
for the --tserver_send_tombstoned_tablets_report_inteval_secs flag,
if needed.

Properly implementing the functionality that KUDU-3486 attempted to add
would be a much more involved patch because there are several items
to address from both the design and implementation standpoints.
