fix the following warning for SkColorTable

../src/core/SkColorTable.cpp: In copy constructor ‘SkColorTable::SkColorTable(const SkColorTable&)’:

Please review.

Interesting. We have gobs of places where we *don't* explicitly call our
inherited constructor (e.g. the function above this one, where we create it with
a count).

I think the warning here is because the compiler sees that this is a
copy-constructor, and SkFlattenable inherits from SkRefCnt, which inherits from
SkNoncopyable, which explicitly hides its copy-constructor.

Perhaps a one-line comment in the code, explaining why we're doing this, would
help.

lgtm
