IMPALA-9568: Template tuples are initialized multiple times

Template tuples are initialized multiple times, concurrently, which
leads to a data race reported by TSAN. The template tuples should just
be initialized once. This patch removes the template tuple
initialization done in the HDFS scanners and just copies them from the
HdfsScanNodeBase.

After this patch, data-load is now TSAN clean. I removed the TSAN flag
'halt_on_error=0' so that TSAN now crashes the process if a TSAN bug is
discovered. This will allow us to setup a Jenkins job that runs dataload
+ be/ tests, and will crash if any new TSAN bugs are discovered.

Testing:
* Ran exhaustive tests
