qemu: caps: Introduce a capability for egl-headless

Browse Source 
Since QEMU 2.10, it's possible to use a new type of display -
egl-headless which uses drm nodes to provide OpenGL support. This patch
adds a capability for that. However, since QEMU doesn't provide a QMP
command to probe it, we have to base the capability on specific QEMU
version.
