log: fix log crash due to missing strdup

ESP32 requires some content as fatal.c rodata to be
placed into RAM to allow cache disabled exceptions.
The consequence is that it will trigger missing log_strdup
call when normal exception is called. Disabling that by default
fix the error and stops terminal output flooding warning event.
