libpng: use GCC visibility to reduce shared library size
The change introduced the implementation for macro PNG_IMPEXP by using
GCC visibility in defaulting of "hidden" attribute.
Experiment on HTC Passion:
target file; out/target/product/passion/system/lib/libskia.so
(libpng was statically linked to libskia.so)
before: 1117888 bytes
after: 1113780 bytes
Code size reduction = 4108 bytes
