Subject: [PATCH] wlheadless: Ignore os.waitpid(-1, 0) error

There's a chance that all child processes have already stopped running
by the time we're cleaning up. If we then try to wait on child processes
to finish (using `os.waitpid(-1, 0)`, the function will throw a
`ChildProcessError`, which makes the whole script fail, with the
following error message:

```
Traceback (most recent call last):
  File "/usr/bin/wlheadless-run", line 90, in <module>
    wlheadless_common.cleanup()
    ~~~~~~~~~~~~~~~~~~~~~~~~~^^
  File "/usr/lib/python3.13/site-packages/wlheadless/wlheadless_common.py", line 151, in cleanup
    self.__cleanup_tempdir()
    ~~~~~~~~~~~~~~~~~~~~~~^^
  File "/usr/lib/python3.13/site-packages/wlheadless/wlheadless_common.py", line 136, in __cleanup_tempdir
    os.waitpid(-1, 0)
    ~~~~~~~~~~^^^^^^^
ChildProcessError: [Errno 10] No child processes
```

Just ignore the error if it happens.
