[SELinux] Allow NNAPI HAL to log traces to perfetto under userdebug builds

Allows DarwiNN NNAPI HAL to log traces to perfetto only under userdebug builds. This is similar to the camera HAL fix in ag/17080874

Error message:
TracingMuxer: type=1400 audit(0.0:486): avc: denied { write } for name="traced_producer" dev="tmpfs" ino=1116 scontext=u:r:hal_neuralnetworks_darwinn:s0

This rule is common for EdgeTPU in both WHI and PRO.

Bug: 231838536

Test: tested on PRO before and after the change, and the traces now shows up.
