ActivityManager: add option to allow OpenGL trace.

This patch adds an option to enable tracing of OpenGL functions.
OpenGL tracing can be enabled by passing "--opengl-trace" option
to am start.  This option requires either a device in debug mode,
or that the application itself has debug permission set.
