[Enhancement] Sliver klist BOF

[Cyb3rC3lt]

I noticed that Sliver didn't have a klist BOF and every time I ran execute -o klist Defender killed my session.

To rectify this I ported OutflankNL's Cobalt Strike BOF to Sliver.

Source code including json and Makefile can be found here:

Hope this helps
