On Ubuntu 22.04, the top-most stack frame is the function
`__pthread_kill_implementation`. Add it to the list of detected functions.
```

```
I did not add a testcase because it would require a specific glibc.

Subject: [PATCH] Fix assert frame recognizer for Ubuntu 22.04
On Ubuntu 22.04, the top-most stack frame is the function
`__pthread_kill_implementation`. Add it to the list of detected
functions.
