AIDEGen: fix atest failure when running aidegen_unittests.

Without config, atest process is blocked in user interactive feature,
and finally failed with timeout.

Bug: 138556212
Test: 1. rm -rf ~/.config/asuite/aidegen/aidegen.config
         atest aidegen_unittests --host
         All tests passed!
