[yocto] [layerindex-web][PATCH 1/2] views: ensure we only show results once in recipe search

Usage of itertools.chain() that was introduced in
3155206e54413f72df3b3b41280eafd332a58ba4 in order to prioritise matches
in the recipe name resulted in recipes showing up twice in the results
if they matched in both the name and the recipe name. Use a custom
chaining function that skips duplicate results in order to fix this.
Fixes [YOCTO #10177].
