ferrochrome-tests: Ensure VmLauncherApp activity is focused
When test fails, event log says that VmLauncherApp is resumed
but the screenshot doesn't show VmLauncherApp.
Instead, audio permission requesting dialog is in the foreground.
To ensure that VmLauncherApp is focused, grant the permission
advance to prevent dialog from being shown.
