chore: remove netstat debugging

[turadg]

refs: #93

We haven't seen that flake since the hypothesized fix #93 (comment)

The debugging output of netstat causes the logs to grow too large for Github's UI to search them. So let's not wait any longer to remove the output.

I don't think this will really solve #93 so this doesn't close it

Curiously, removing the debugging output re-triggered the error I thought was fixed:

#0 1.611 Error: failed to listen on 0.0.0.0:26657: listen tcp 0.0.0.0:26657: bind: address already in use
#0 1.611 8:45PM ERR pprof server error err="listen tcp 127.0.0.1:6060: bind: address already in use"

	apt install net-tools
	netstat -plnA inet
	# precondition check

This PR is to remove the netstat debugging. The underlying cause is that agd is already bound to the ports. I don't know the cause of that but this hacks around it by waiting for it to die.

Right, I'm trying to get to the bottom of that with a more useful invocation of netstat.

Oh, I thought you were suggesting a change in this PR. If you want to figure out the cause of failures in #127 I thought you'd push to that branch whatever logging you need.

I'm putting this up for review again because I think we should keep those netstat logs out of main. They make the logs unwieldy to scroll in the Github UI

merging without review to help debug trunk.
