media-gfx/pngcrush: only use PNG_IGNORE_ADLER32 if supported
Since libpng-1.6.41 support for PNG_IGNORE_ADLER32 is optional, disabled
by default owing to its use of an undocumented zlib function, and not
presently enabled in Gentoo.
Funnily enough there are *two* places in pngcrush code where this option
is used and one of them has already used an ifdef guard.
