Removing unwanted files from Dockerimage, Fixing duplicate files

New Findings - 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 xray-indexer 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 xray-indexer image, we have bundled it a single time only.

This will improve the current Overall Risk Assessment Score.
