linux-wrs: Fix qemux86-64

Browse Source 
Use the fragment support provided by kern-tools in the linux-wrs recipe to add
some extra modules required for qemux86-64 such as evdev and uvesafb.

Add a patch to increase CONNECTOR_MAX_MESSAGE_SIZE as uvesafb was sending
larger messages than the kernel would accept.
