VIGS: add synchronous glReadPixels fallback

On some GPUs accessing OpenGL objects from different threads
may lead to a deadlock inside the host video driver (e.g. AMD
Radeon FGLRX). To workaround this problem new env var has been
introduced: VIGS_SYNC_READ_PIXELS. It makes VIGS use a single
work_queue for both rendering and pixels reading.
