glmark2: Remove X11 exclusiveness

The tool has support for multiple backends: X11, drm and Wayland.

This demanded to a fix, which has been sent upstream, to make the
flavor configuration predictable and the recipe has been rework to
support them all, making the PACKAGECONFIG to respect the
DISTRO_FEATURES available by default.

+From: Otavio Salvador <otavio@ossystems.com.br>
+Subject: [PATCH] build: Check packages to be used by the enabled flavors
+Organization: O.S. Systems Software LTDA.
+
+The packages shouldn't be dynamically detected otherwise the build
+predictability is lost. We now have all packages as mandatory but
+dependent of the flavors which use them.
