Remove obsolete config variable 'HAVE_LIBPNG_PNG_H'
This variable has never been used in the code. Configure and CMake look for a *working* libpng (HAVE_PNG) and set variable HAVE_PNG_H if the header <png.h> can be included. The alternative to include <libpng/png.h> is always used in the #else clause and doesn't need its own config variable. Configure and CMake log what they find, hence this extra variable is not necessary.
