[PATCH v2 01/14] KVM: selftests: Build and link sefltests/vfio/lib into KVM selftests

[Josh Hilke <jrhilke@google.com>]

From: David Matlack <dmatlack@google.com>

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

Note that KVM selftests build their own copy of sefltests/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.
