infra: stop patching llvm-symbolizer (#5839)

* infra: stop patching llvm-symbolizer

to prevent it from failing to start up with
```
NEW_FUNC[1/1]: llvm-symbolizer: symbol lookup error: /tmp/not-out/instrumented_libraries/lib/x86_64-linux-gnu/libz.so.1: undefined symbol: __msan_va_arg_overflow_size_tls
==45==WARNING: external symbolizer didn't start up correctly!
```

Closes https://github.com/google/oss-fuzz/issues/5349

* infra: reformat patch_build.py with yapf

to make the presubmit check happy
