Attempt to fix bitcoin reorg flap test

[obycode]

Forcefully kill the bitcoind in case it fails to stop.

[obycode]

It looks like some change in between the original fix to this problem and the current next has caused the test to fail, so that needs to get fixed. I'll look into it tomorrow.

this PR still needs more work. brice and I have discussed some alternatives but it may not be ready for 2.5.

i would recommend we move this to draft/backlog for now

@obycode Can we close this? I think you got this working recently by using an RPC to bitcoind to make it stop?

[obycode]

Yes, this was fixed by #5207.
