Add lockbud to CI

[eserilev]

Adds lockbud to CI w/ one caveat

The caveat is the CI job never actually fails. Even if a deadlock is found, it'll just log the deadlock in CI, but wont return an error code. We have an issue up in LH here to eventually fix this

So yeah, not the most ideal CI job... but still might be nice to have until we get the job to fail correctly

@eserilev do you have a way to reproduce this - as in some sample rust that will trigger output from lockbud?

If yes, I can try get it to fail the workflow.

@magick93

you should be able to force a deadlock with the following snippet
https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=89b90214fbcb364bd9ac5ccaf4ff7d01

If its easier you can revert the changes in this commit here in LH:
sigp/lighthouse@101bf81

lockbud will report a deadlock

@magick93, I have introduced such a failure: https://github.com/sigp/anchor/actions/runs/12806469752/job/35705033682?pr=83#step:5:1312 - hope it helps!
