gnome: add support for the OIL Runtime Compiler (ORC) optimized code execution

Add a new gstreamer_orcexec_t type and file context to the gnome
module in order to support the OIL Runtime Compiler (ORC) optimized
code execution (used for example by pulseaudio).

Add optional policy to the pulseaudio module to support the ORC
optimized code execution.

This patch has been anticipated a few weeks ago as part of a
larger gnome patch. It has now been split as a smaller patch,
as required.
