[PATCH libinput 9/9] Add libinput_device_get_name() to advertise the kernel name

I didn't end up needing this but it seems a nice to have. However, it does
lead to a discussion on how much of the device should we expose to the
caller through libinput.

Right now libinput hides virtually everthing but the sysname and even that
may not be enough to even get a udev reference. It is enough for now though
because we only handle one subsystem.

If a caller needs settings or get other information on the device, they need
to be able to query udev or the fd, but the latter then needs 
needs open_restricted-like hooks.
