[libvirt] [PATCH] build: Require cppi for syntax-check

Since its introduction in v0.8.0~314 we allowed for cppi to be not present for 'syntax-check' because the package did exist in Fedora Core 12. Well, we don't care anymore ¯\_(ツ)_/¯ All recent distros have it. Moreover, it's fairly easy to miss 'cppi not installed' message in sea of syntax-check output (esp. for newbies who probably benefit from it the most).
