package: Add libmanette

libmanette is a library which provides a higher level interface to
enumerate and make use of game controllers (gamepads, joysticks).
WebKitGTK can use libmanette to expose controllers to web content,
which will be enabled on a follow-up patch.

Minimal kernel headers 4.16 for input_event_sec and input_event_usec
in struct input_event.
