Use base::WrapUnique in CanonicalCookie factory methods.

This is part of an effort to make CanonicalCookie's constructor private.

Since make_unique<T> will not compile if T's constructor is private, we
need to replace uses of make_unique in CanonicalCookie's implementation
with base::WrapUnique() and the "new" keyword.
