Fix Equals and serialization for rare pngs

PNGs may contain a gAMA chunk that specifies gamma
values as floats.  If so, we will use these floats
to create an SkColorSpace.

This CL fixes Equals(), serialize(), and
Deserialize() to correctly handle SkColorSpaces
with strange gammas, where we are unable to fall
back on the profile data.
