I only converted the cases that use common.qemu, so they failed after
my change. The other test cases you found are running qemu manually and
didn't apply the filter yet, so they wouldn't fail.

For v2, I'll add the new filter to them and change the reference output
accordingly.

I'll use your bash version in v2.
