[Cogl] [PATCH] gl: #ifdef guard ARB_sync api in cogl-all-functions.h

[Robert Bragg]

From: Robert Bragg <robert at linux.intel.com>

The ARB_sync api depends on a GLsync type which may not be available if
GL_ARB_sync isn't defined, such as when building for gles2 only. This
guards the prototypes with #ifdef GL_ARB_sync to fix compilation when a
GLsync type isn't defined.
