We can't distinguish but after the first CI reports if a machine that
had PSR2 tests running suddenly start to skip PSR2 tests it will be
reported by CI.

Ohh now I got what you want to do, looks good I will change to this.
But we will need to generate PSR2 tests for every machine, as the
igt_fixture() do not run when getting the list of subtests and CI
probably uses that to split the tests through the shards.
