support/testing/tests/package/test_fwts.py: switch to neoverse-n2 cpu

The SBSA Reference Platform was updated to neoverse-n2 (armv9.0a)
in Qemu v9.1 [1].

The Armv9-A and Neoverse N2 core support was added in Buildroot
commit [2].

Since the test_fwts uses the Qemu sbsa-ref machine, this commit
aligns it to use the neoverse-n2 cpu.
