libinput: Remove duplicate patch already fixed upstream

Under certain conditions libinput created duplicate device entries and
thus broke our touch system.
This is now fixed upstream and we can remove the patch and the bbappend file.

-Subject: [PATCH] Fix race condition causing duplicate devices in udev seats
-
-There is a race between adding the udev monitor and enumerating current
-devices. Any device added in that window will show up in both lists, causing
-it to be added twice.
-
-Fix this by comparing the syspath of any added device to the existin ones in
-the seat - where it matches we can ignore the device.
-
-Fixes #459
