[android] Don't print debug messages at startup (#54221)

The JNI_OnLoad method calls GetClassGRef and GetMethod several hundred times
during startup.  The debug output is redundant (if any classes or methods are
missing we will assert and print a message and kill the process) and it slows
down startup.
