stx-vault-helm causes build failure

[Lucas]

Brief Description
-----------------
Centos build of StarlingX master branch is failing on the build-iso step.

Could not resolve packages: stx-vault-helm-armada

It appears this package was being removed by update ...

https://review.opendev.org/c/starlingx/vault-armada-app/+/853822

... but something was missed.

I suspect the stx-audit-helm-armada reference in centos_iso_image.inc .
