Add an API interface to access the ImagePath of the process triggering a hook

### Describe the feature you'd like supported

Allow for an ebpf program to access the full path of the process triggering the hook, similar to [bpf_get_current_comm](https://docs.ebpf.io/linux/helper-function/bpf_get_current_comm/) which only gives the process name without the full path.

### Proposed solution

This is useful to make decisions based on the process name directly on the ebpf program, without relying on process ids which can be dynamic, or depend on user-space logic.
