IMPALA-14382: Fix Null Pointer Dereference
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.

> Issue Type: Bug
> Reporter: Jason Fehr
> Assignee: Jason Fehr
> Priority: Critical
>
> When log level is set to 2 or higher, a null pointer dereference and a
> minidump can happen with a RELEASE build during the EE tests in
> [BaseSequenceScanner|https://github.com/apache/impala/blob/master/be/src/exec/base-sequence-scanner.cc#L125].
> To reproduce this issue, build Impala in release mode and run test_scanners:
> {code:sh}
> ./buildall.sh -notests -release
> ./tests/run-tests.py query_test -k 'test_scanners'
> {code}
