rpi-userland: add patch fix missing libvcilcs install rules

This change adds a patch fix the missing install rules for libvcilcs.

This is a pre-requisite to be able to build the shared libraries of the
rpi-userland package, and most importantly avoid linkage failure (at
link-time and/or runtime) in others libraries that link with it.
