IMPALA-13015: Dataload fails due to concurrency issue with test.jceks

Move 'hadoop credential' command used for creating test.jceks to
testdata/bin/create-load-data.sh. Earlier it was in bin/load-data.py
which is called in parallel and was causing failures due to race
conditions.

Testing:
- Ran JniFrontendTest#testGetSecretFromKeyStore after data loading and
test ran clean.
