    win32: Minor build fixes for building for win32
    
    This fixes some minor errors and warnings that were preventing Cogl
    building with mingw32:
    
    • cogl-framebuffer-gl.c was not including cogl-texture-private.h.
      Presumably something else ends up including that when building for
      GLX.
    
    • The WGL winsys was not including cogl-error-private.h
    
    • A call to strsplit in the WGL winsys was wrong.
    
    • For some reason the test-wrap-rectangle-textures test was trying to
      include the GDKPixbuf header.
