Update to latest Parca standards

This project has been asleep for a bit.
Compiling and running generally seems mostly fine.

It however fails to convert the profiles with some proto error.
```
msg="convert failed" pname=rcu_par_gp error="pprof failed: exit status 1, stderr: Unknown option: proto\nInvalid
```

We might also want to consider updating the flags to the parca / parca-agent flags for familiarity.
