Tools such as sysdig[0] have the ability to deploy BPF probes across a Kubernetes cluster. However part of the setup scripts for this require access to the kernel config and on Thar this isn't available in any of the common locations. CONFIG_IKCONFIG makes the config available regardless of where the setup is being run and is a well known source, so switch it on for Thar.

Description of changes:
Tools such as sysdig have the ability to deploy BPF probes across a
Kubernetes cluster. However part of the setup scripts for this require
access to the kernel config and on Thar this isn't available in any of
the common locations. CONFIG_IKCONFIG makes the config available
regardless of where the setup is being run and is a well known source,
so switch it on for Thar.
In particular for sysdig, the config is required to determine the expected
name of the precompiled probe, without which it will refuse to load.
