No entry in logcat after dlopen returns valid address

The issue is as mentioned above. The following output confirms that the library was loaded in the remote process.

```
beryllium:/data/local/tmp # ./injector 15449 libhook.so
@ Injecting library libhook.so into process 15449.

@ Calling dlopen in target process ...
@ dlopen returned 0xA8F8DD10
```
However, there are no entries in logcat, both in the script and in a separate terminal.
