Jinchul 2fba80ee5e IMPALA-5146: Fix inconsitent results at FROM_UNIXTIME() ...

The FROM_UNIXTIME(epoch) and FROM_UNIXTIME(epoch, format) produce
different results when epoch is out of range of TimestampValue.
The former produces an empty string, while the latter gives NULL.

The fix is to harmonize the results to NULL.

Testing:
Add unit tests to ExprTest.TimestampFunctions.
