wayland: Use dev/evdev/input.h on FreeBSD

The header linux/input.h used by GDK is specific to Linux. It is
possible to get a few Linux headers on FreeBSD by installing v4l_compat,
but it is usually better to use the one shipped with FreeBSD.

We prefer dev/evdev/input.h to linux/input.h here, so it will always use
dev/evdev/input.h on FreeBSD regardless of v4l_compat.
