0-auto-detect: keep module loading order as before

Commit bdf2b690 uses 'sort -u' which changes module loading order.
It causes some issues. For example, on a device with two graphic
cards, the driver of the discrete graphic card may be loaded first
that causes black screen issue.

Use the simple awk script to remove duplicate items but keep the
order unchanged.
