clutter-actor: Don't apply shaders during picking
clutter-actor: Don't apply shaders during picking

Commit 0ede622f5132 inadvertently made it so that shaders are applied
during picking. This was making test-shader fail to respond to clicks.

The commit also makes it so that culling is applied during
picking. Presumably this is also unintentional because the commit
message does not mention it. However I think it may make sense to do
culling during picking so it might as well stay that way.
