[Buildroot] [PATCH 3/5] package/qt5: fix EGLFS for embedded boards

[Einar Jon Gunnarsson]

Note that on some boards the special value of none is
used instead of an actual plugin. This indicates that
no special integration is necessary to use EGL with the
framebuffer and so no plugins must be loaded.
