switch: for surface 3 tablets, write the lid open to the device

These tablets only ever give us a close event, the open event is broken. So
when we detect keyboard events, fix the kernel device's state by writing the
event to the fd.

We still sync the lid state manually, in case this fails and we don't get the
SW_LID through the normal event sequence. If it works fine, the real open
event will just be ignored.
