vlib: clean up the "pcap dispatch trace" debug CLI

Browse Source 
Separate debug CLI arg parsing from the underlying action
function. Fixes a number of subtle ordering dependencies, and will
allow us to add a binary API to control the feature at some point in
the future.

Type: refactor
Ticket: VPP-1762
