Raphael Isemann 4f244bba4f [lldb] Fix asan failures in data-formatter-objc tests 
The test is currently failing on some systems with ASAN enabled due to:
```

```

The reason is that we create a string "HELLO" but get the size wrong (it's 5 bytes instead
of 4). Later on we read the buffer and pretend it is 5 bytes long, causing an OOB read
which ASAN detects.

In general this test probably needs some cleanup as it produces on macOS 10.15 around
100 compiler warnings which isn't great, but let's first get the bot green.
