Remove custom logic to skip configuration of gripper_controllers on Windows or macOS

[traversaro]

The gripper_controllers package was disabled on macOS and Windows as it used experimental/optional, but it does not seems to me that the header is used anymore, and I just tried to compile it on Windows and it compiled fine.

Fix #193 .

Awesome. I'm glad that it works. Then let's also export all the symbols as other controllers
