Fix skshaper in component builds

It was building a shared library, but had no exports (on Windows).
We think the correct model for modules in the future is for each one
to be a separate DLL linked against the public API/exports of Skia.
This serves as the model for that. Doing this with other modules will
probably require exporting more symbols from Skia.
