The `.baremetal-arm64-asan-test` job extends `.baremetal-test` and
`.use-debian/baremetal_arm64_test` but doing this is unnecessary because
all of the arm64-asan jobs also inherit the `.baremetal-test-arm64` job
which does the same thing.
Furthermore when `.baremetal-arm64-asan-test` appears last in the list of
extended jobs, as in the case of the `a630-gles-asan`, the general rules
inherited by `.baremetal-arm64-asan-test` override the more specific
driver rules and prevent the driver job from appearing in the merge
pipeline.
Simply bumping the `.baremetal-arm64-asan-test` job back earlier in the
list of extended jobs would allow the driver rules to take precedence but
then the S3_ARTIFACT_NAME, provided by `.baremetal-arm64-asan-test`, which
is specific for asan builds, is overridden.
By removing the inherited jobs from the `.baremetal-arm64-asan-test`,
this job can continue to provide the asan artifact without interfering
with the driver jobs appearing in the merge pipeline.
