Google Play is now blocking distribution for Android TV unless we
explicitly set the android.hardware.microphone hardware feature as
android:required="false", because it's inferring
android.hardware.microphone from the android.permission.RECORD_AUDIO we
added for Wii Speak emulation, with android:required defaulting to true.
I was under the belief that setting android:required="false" on
android.permission.RECORD_AUDIO would solve this, but looking closer at
the definition of <uses-permission>, it doesn't actually support
android:required attributes, so that presumably has no effect.
