Subject: [PATCH 29/31] perf kvm: Move kvm-stat header file from conditional inclusion to common include section

From: Anju T Sudhakar <anju@...ux.vnet.ibm.com>

Move kvm-stat header file to the common include section, and make the
definitions in the header file under the conditional inclusion `#ifdef
HAVE_KVM_STAT_SUPPORT`.

This helps to define other 'perf kvm' related function prototypes in
kvm-stat header file, which may not need kvm-stat support.
