Whitelist some of our own broadcast actions

* Starting with Oreo, all the apps that target O+ are always subject to
   background restrictions (android/platform_frameworks_base@42a386b7717300bf6d75cbd3b4f7ad00f294be0d).

   The manifest-registered receivers of apps with a targetSdkVersion
   higher than 25 won't receive the broadcast. Instead, a message similar
   to the following will appear in LogCat:

       10-07 14:13:49.594   719   736 W BroadcastQueue: Background execution not allowed: receiving Intent { act=lineageos.intent.action.LID_STATE_CHANGED flg=0x20000010 (has extras) } to org.lineageos.flipflap/.EventReceiver

 * Exempt some of our broadcast actions so that we can keep targetting
   the latest SDK.
