Make inputflinger permissive or unconfined.

Otherwise we'll never see denials in userdebug or eng builds and
never make progress on confining it.  Of course we cannot truly
test until it is released into AOSP, but this prepares the way
and potentially allows for internal testing and collection of denials.
