Darwin: enable non-exclusive device usage

[ilyalasy]

So it seems that all we need to do is export the following functions and set them accordingly.

void HID_API_EXPORT_CALL hid_darwin_set_open_exclusive(int open_exclusive)

int HID_API_EXPORT_CALL hid_darwin_is_device_open_exclusive(hid_device *dev)
