  EGL: Force mythfrontend to use EGL when available for VAAPI/MMAL

- VAAPI with EGL/DRM is much faster than the GLX version and is hence
preferrable
- we can only try and force this by setting the appropriate environment
variable early in startup
- NVidia installations are unaffected
- should enable VAAPI interop on Wayland (which as no GLX - hence no
fallback from DRM to GLX interop)
- also required for Raspberry Pi with MMAL direct rendering (Note: only
needed for desktop - EGLFS will already be compatible)
- use the environment variable NO_EGL to disable (but shouldn't be
needed)
- also remove some older Pi only clearing of the QT_XCB_GL_INTEGRATION
variable. We need to clearout all of the Pi workarounds to try and get
functioning playback on different setups - both opensource driver (VC4)
and Broadcom closed source - all of which is horribly complicated by the
Qt version in use (whether it links to the open or closed source
drivers)
