linux-yocto/xen: update fragment to support both dom0 and typical xen guests.

Browse Source 
Updated linux kernel fragment to match defaults as defined in the 3.10 kernel's Kconfig files.  If defaults were not specified, modules were were used unless required by another built-in option.  As such, The core frontend drivers are included by default and the backend drivers are built as modules.

This allows privileged, PV, HVM, and PVHVM guests to work properly without additional kernel configuration or modules required in initramfs (from a Xen support perspective).

This also removes CONFIG_KVM_GUEST which was erroneously included previously.
