ghostscript: 9.16 -> 9.18

- Backport patches to fix build failure caused by
  '--without-jbig2dec' and '--without-jbig2dec'.
  ...
  |make[1]: *** No rule to make target `obj/sjbig2_.dev',
  needed by `obj/sjbig2.dev'.  Stop.

- Previously, it did not build the whole local libpng
  source in ghostscript, only picked up specific files
  and compile them. But on ghostscript 9.18, when the
  arm's FPU has been set to NEON (-mfpu=neon * with GCC),
  the selected file "libpng/pngrutil.c" needs to link
  'png_init_filter_functions_neon' which should be
  compiled by a non-selected file "libpng/arm/arm_init.c".
  ...
  |./obj/pngrutil.o: In function `png_init_filter_functions':
  |armv7a-neon-poky-linux-gnueabi/ghostscript/9.18-r0/build/../
  ghostscript-9.18/libpng/pngrutil.c:3921: undefined reference to
  `png_init_filter_functions_neon'
  ...
  So do not compile local libpng source in ghostscript,
  use shared libpng to instead.
