[client] egl: use standard-compliant way of EGL detection

Browse Source 
According to the documentation for eglQueryString:

> EGL_BAD_DISPLAY is generated if display is not an EGL display connection,
> unless display is EGL_NO_DISPLAY and name is EGL_EXTENSIONS.

Therefore, we should check EGL by doing:

    eglQueryString(EGL_NO_DISPLAY, EGL_EXTENSIONS)

Indeed, the old way of eglQueryString(EGL_NO_DISPLAY, EGL_VERSION) works on
libglvnd but not using mesa's libEGL.so directly.

Also added a warning to make it more obvious that EGL is not available.
