An app can host widgets only if it has a special signature premission or the user allowed this app to be able to bind to widgets. This change grants the permission to whitelist an app to bind to app widgets to the shell user. Now a test can have a host that will have some widgets. Note that this is different from whitelisting corp widgets. bug:17993121 Change-Id: Ic6b866cb2a822254e94a130b876ee5db66ed4fbf
