From: Dmitry Osipenko <dmitry.osipenko@collabora.com>

New virglrerenderer features were stabilized with release of v1.0.0.
Presence of symbols in virglrenderer.h doesn't guarantee ABI compatibility
with pre-release development versions of libvirglerender. Use virglrenderer
version to decide reliably which virgl features are available.
