v2022: lava: amd64-upsquared6000: Use v2022 1st stage image with firmware pkgs

The latest Apertis NFS images now include firmware pkgs required to
enable audio and the Intel AX210 wifi module on the UP Squared 6000
board.

Without these firmware pkgs, drivers will retry several times. Thus,
lots of kernel msgs are printed to the serial console, which makes LAVA
test fail to parse the login prompt.

Since we are currently in the release period and this is adding a lot
noise to the results, let's use the latest daily image. But note that
this should be updated quickly to a weekly release, before it becomes
unavailable.
