KVM: selftests: Build and link selftests/vfio/lib into KVM selftests

Browse Source 
Include libvfio.mk into the KVM selftests Makefile and link it into all
KVM selftests by adding it to LIBKVM_OBJS.

This lays the groundwork for future changes to utilize VFIO devices to
verify IRQ bypass in KVM selftests.

Note that KVM selftests build their own copy of selftests/vfio/lib and
the resulting object files are placed in $(OUTPUT)/lib. This allows the
KVM and VFIO selftests to apply different CFLAGS when building without
conflicting with each other.
