Revert "GraphicsEnvironment: Allow profileable apps to load layers"

This reverts commit 3832aa99.

Loading layers for apps that have opted for "profileable" breaks
the Android security model.  They have only consented to exposing
profiling information, not exposing data under its control.  Layers
have access to everything in the API calls.
