[kudu-CR] Update build pattern for fetching flaky tests list

Hello Zoltan Chovan, Alexey Serbin, Ashwani Raina, Attila Bukor, Kudu Jenkins,

to look at the new patch set (#5).

Change subject: Update build pattern for fetching flaky tests list

Update build pattern for fetching flaky tests list

During the infra changes which happened in the last months, the build_id
prefix has been changed [note 1]. As a result flaky tests are not
retried during testing in the pre-commit runs. This patch updates the
build pattern in the build-and-test.sh script, such that the
list of flaky tests is fetched correctly.

[note 1]:
The build_id of an isolated test is constructed with Jenkins job's name
and build number, prefixed with "jenkins-". To illustrate this let me
give some examples, for build_ids prior and after the infra upgrade.
Before:
jenkins-kudu-gerrit-BUILD_TYPE=ASAN-29232
jenkins-kudu-gerrit-BUILD_TYPE=DEBUG-29227
After:
jenkins-build_and_test-64
jenkins-build_and_test-63
From the above we can see that the new Jenkins job name caused the
issue. The new job is parametrised, does not contain the build type in
the job's name. Therefore, a change in the naming is justified.
In case something like this happens in the future, the build_ids can be
observed in the test_results MySQL database on the isolateserver test
infra host.
