Revert "kola/tests: Skip tests that change the verity hash when SB is…

… enabled"

This reverts commit b583d18. I
misunderstood what these tests do. Booting is supposed to fail after
changing the verity hash, but then it is supposed to successfully fall
back to the other partition. The tests were failing due one of Red Hat's
GRUB patches. We have now fixed this.
