Consider using hugepages for the TailsToaster VM

This should improve the test suite performance quite a bit. Given some tests configure that VM with 8 GiB of RAM, we would need to pre-allocate 8 GiB of hugepages, and then it would be impossible to run the test suite on a system that has less memory. I don’t think it is a blocker as relying on swap to run these tests will likely make them timeout or be too slow to be practically useful.
