wifi: Fix flake test of mock wifi
1. Rename mocked AP name to instead of "GoogleGuest" because it may cause
incorrect test result since it is an existing AP in some test environments.
2. Add mock scan ready event to force the wifi frameworks get mocked scanresult.
3. Reduce polling timeout since mocked scan result is available only 10 seconds.
