Reason for Change

The /dev/ubsan directory on the device is used to archive UBSan logs. With DFX integration, logs are saved to the /data/log/faultlog/faultlogger directory. The /dev/ubsan directory is no longer required.
The /dev/ubsan directory cannot isolate read and write permissions among different users, which poses security risks.

Change Impact

This change is a non-compatible change.

The /dev/ubsan directory can no longer be read or written.

Change Since

OpenHarmony 5.0.0.46
