    egl-gdl: Don't generate cogl-display.h
    
    It's not necessary to generate cogl-display.h just for the GDL backend
    and to change the inclusion of libgdl.h. We can just tweak the include
    CFLAGS to put /usr/include/CE4100 in the search path when needed.
    
    Previously this did not work because of a stay ',' at the end of the
    COGL_EXTRA_CFLAGS int he configure.ac. This actually simplifies the
    code, which is always good.
    
    This also fixes out of tree builds.
