IMPALA-14382: Fix Null Pointer Dereference

Browse Source 
Fixes a potential null pointer dereference when log level >= 2.

Adds 'build' as a valid EE test helper directory as VSCode creates
this directory.

Tested locally by running test_scanners from the query_test EE test
suite using a release build of Impala and log level 2. Minidumps were
not generated during this test run but were generated during the same
test run without this fix applied.
