Removing src/backend from include path might break on HPUX

Now that we don't -I...backend anymore, this might break:

src/include/c.h:

#ifdef FIXADE
#if defined(hpux)
#include "port/hpux/fixade.h"   /* for unaligned access fixup */
#endif   /* hpux */
#endif

The comments surrounding this make it pretty unclear whether this is still
necessary. Tom, any idea?
