patch 9.0.1713: Github CI fails to load snd-dummy kernel module

Problem: Github CI fails to load snd-dummy kernel module
Solution: Make installation of linux-modules-extra optional

linux-modules-extra package are not available on Ubuntu 22 at the
moment, which breaks CI runs. The change make its installation
conditional as the original `if-else` structure tried to do.

closes: #12801
