Jia Hao 2b0b0a0e78 Log dlopen errors in opt builds (flutter/engine#41477)
As the Engine uses `dlopen` to find the `libapp.so`, https://github.com/flutter/flutter/issues/59834 can happen which will prevent `dlopen` from finding the binary. In theory this should be mitigated by https://github.com/flutter/engine/pull/9762, but an internal customer observed errors that could be related. 

The additional logging here can help to rule out that hypothesis. For Googlers, see b/276657840 for more details.
