pyroscope.java: Fix java log level parameter (#4440)

* pyroscope.java: Fix java log level parameter

The version bundled of the async profiler has no loglevel parameter:

```
ts=2025-09-16T08:16:50.898924708Z level=error component_path=/profiling.feature component_id=pyroscope.java.java_pods pid=1184752 err="failed to start: asprof failed to run: asprof failed to run /tmp/alloy-asprof-ae0261b1093f2bc4df44a87300fef98dcdebccb5/bin/asprof: exit status 1  Unrecognized option: --loglevel\n"
```

* Quiet is not a valid argument for the async-profiler cli

It can only be used for attaching using agent
