qtbase: Disable eglfs build for i.MX6 SoCs using X11
The eglfs hooks require the Framebuffer API calls which are not
available when building for X11; to allow qtbase to build for X11 we
must disable eglfs support due this restriction.
A patch to workaround EGL initialization failure due visual mismatch
has been included as well, forcing Visual ID 33.
