Remove unneeded sysdig image patching

[jgarcows]

Description

Because of a defect in the IBM Observability code, sysdig images used to need to be patched to be from the appropriate icr.io/ext/ repository. The defect has been fixed for a long time in the IBM Observability code, and now this patch is preventing IBM Observability from switching to the slim sysdig agents (icr.io/ext/sysdig/agent-slim).

Removing the forced image rename allows the IBM Observability code to function as expected and provide a consistent experience between schematics, UI, and CLI users.
