Removing unwanted files from Dockerimage, Fixing duplicate files

Removing extra diagnosticUtil binary from iron-bank image, also removing /script folder from dockerfile

We can see that diagnosticsUtil is bundled twice in iron bank images,

For example In Artifactory pro it is available at path /opt/jfrog/artifactory/app/bin/diagnostics  but at one more place it is present/opt/jfrog/artifactory/app/bin/ . Please take a look /opt/jfrog/artifactory/app/bin/  this can be removed

In artifactory pro  image we have bundled it single time only.

This will improve current Overall Risk Assessment Score as well.
