libpng: update to 1.6.1
This attempts to fix [YOCTO #4060] - connman-applet spews warnings, but with this one PNG images still don't work in weston :(
The ARM NEON option was added because the autodetection code in configure.ac is broken:
/usr/lib/weston/weston-desktop-shell: symbol lookup error: /usr/lib/libpng16.so.16: undefined symbol: png_init_filter_functions_neon
License checksums update due to date and package version changes:
