Allow edgetpu_tachyon_service to call mlock()

Browse source 
Tachyon AIDL service is the new Darwinn runtime v3. It needs mlock capability to support the GenAI effort, allowing file backed large models to be mlocked, satisfying the memory accounting on Android, similar to what we just did for edgetpu_app_service ag/26481028

Bug: 337949682
Test: On-device tested that tachyon service can now lock large memories.
