[PATCH 1/1][SRU][H][OEM-5.10] firmware/dmi: Include product_sku info to modalias

[AceLan Kao]

From: Kai-Chuan Hsieh <kaichuan.hsieh at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/1938143

Some Dell platforms rely on modalias to customize configuration,
the product sku can be more specific for the hardware.

Add product_sku to modalias for better utilization.
