kmscon: split the OpenGL ES path into kmscon-mod-gl - #165

kmscon depends on a libmesa provider, so every system with a KMS console pulls in Mesa, but the main binary links none of it: the GL code lives entirely in mod-drm3d.so and mod-gltex.so, which are dlopened from a directory scan of the module directory. The software renderer bbulk is built into the binary, the drm2d backend needs only libdrm, and hwaccel is off by default, so Mesa is unused on a default install and the modules are absent-tolerant by construction. Ship those two modules as kmscon-mod-gl and build them only when it is selected. A system that carries Mesa for other reasons installs the package and starts kmscon with --hwaccel; everything else gets a console with no Mesa in the build at all.
