Does this even work? I suppose that we do have a minimal version syntax
for commands but not for mkfs.foo. And even for commands the version
parser needs to be implemented for each command separately. We have one
for mkfs.ext4 at the moment.

I suppose that we need to add .mkfs_ver string to the struct tst_fs and
possibly .kernel_ver as well so that we can add both checks to the
structures as:

	{
		.type = "xfs",
		.mkfs_ver = ">= 5.1.0",
		.kernel_ver = ">= 4.9.0",
		...
	}
