optipng: switch to bundled zlib and libpng

Browse Source 
Benefits:
 - newer versions of the libraries
    - zlib: 1.2.8 -> 1.2.11
	- libpng: 1.6.18beta04 -> 1.6.34
 - much fewer dependencies to install (as libs are already in optipng archive and we don't need napa)
 - much smaller build thanks to customised versions of zlib and libpng containing only APIs necessary for optipng itself: 238950 -> 177359 bytes
 - much faster build thanks to preconfigured libpng and stripped APIs: 2m15s -> 40s
 - much simpler build script: 77 -> 46 lines
