[PATCH] uapi: add missing install of userio.h

[Naohiro Aota]

While commit 5523662edd4f ("Input: add userio module") added userio.h
under the uapi/ directory, it forgot to add the header file to Kbuild.
Thus, the file is missing from header installation. This patch just
resolve the issue by adding the missing entry.
