Log dlopen failures caused by text relocations

Some apps will fail to load native libraries with
text relocations when switching target sdk version to M.
It could be hard to diagnose because some of them
suppress dlerror and/or UnsatisfiedLinkError.

This change unconditionally logs the error message making
the cause of the failure more visible to developers.
