qtbase: use platform-specific qt5.sh scripts instead of backend-specific ones

We have specific scripts per platform to export the qt5 environment variables,
because using the default backend-specific scripts ported from the meta-imx
layer results in mismatches in specific cases (for example, 6UL framebuffer
images only support linuxfb, but the qt5-fb.sh script exports eglfs instead).
