Uninstall eBPF using Uninstall-Package

To attempt to make eBPF uninstall more resilient to various errors, uninstall using Uninstall-Package if the local MSI uninstall failed.

netperf jobs still fail to remove eBPF:

Yeah, I'm not really surprised. I've seen plenty of cases on my own test machines where a bugcheck causes the eBPF MSI to be "not installed" but the eBPF service and driver are still installed, requiring manual steps (e.g. sc delete) to uninstall.

I am enabling verbose output in the netperf jobs so we can verify the behavior of the MSI changes here.
