tests/k8s: add k8s-measured-rootfs.bats

Implements the following test case:

  Scenario: Check incorrect hash fails
  **Given** I have a version of kata installed that has a kernel with the
  initramfs built and config with rootfs_verity.scheme=dm-verity
  rootfs_verity.hash=<incorrect hash of rootfs> set in the kernel_params
  **When** I try and create a container a basic pod
  **Then** The pod is doesn't run
  **And**  Ideally we'd get a helpful message to indicate why

Currently on CI only qemu-tdx is built with measured
rootfs support in the kernel, so the test is restriced to that
runtimeclass.

Fixes #7415
