Modifications to get skia headers compiling on iOS.

Modifications to get skia headers compiling on iOS.

This is a barebones implementation of the skia target in skia.gyp.  iOS will not
use a full skia implementation, but it will use an occasional header here and
there.  Those headers require an implementation of SkDebugf_FileLine(), so this
CL adds a barebones skia target that simply compiles skia/ext/google_logging.cc.

How about moving this down to just before "android" so there's less bouncing
between OS ifs and flag ifs.

If OS == 'mac' it is likely to be != from ios as well, the second part of the
condition is redundant.
