Remove android.hardware.neuralnetworks@1.X dependencies.

After moving NNAPI to an APEX, android.hardware.neuralnetworks@1.X
were added as explicit dependencies to enable NNAPI static tests
to run.

It's possible to make them included in NNAPI static tests as static
libraries, no point in keeping them here.
