build: Exclude COGL_DEFINES and COGL_GL_HEADER_INCLUDES from Makefiles

Browse source 
Some variables (notably multiline ones) are not really supposed to be
substituted by automake. Let's take COGL_DEFINES for instance, you get:

  COGL_DEFINES =
  #define COGL_HAS_GLIB_SUPPORT
  #define COGL_HAS_GTYPE_SUPPORT
  #define COGL_HAS_GL
  #define CLUTTER_COGL_HAS_GL
  #define COGL_HAS_GLX_SUPPORT
  #define COGL_HAS_SDL
  ...

This only works because the '#' character makes it look like a comment
and COGL_DEFINES becomes an empty variable

Automake allows to exclude variables from the list of substitutions,
let's use it for those two.
