242949ecfb fix(tvix/tests/tvix-init): run as pid1, support init=
We were previously not running as PID1, but were executing things via
uinitcmd (by u-root init).
This had some problems - a real system pid1 really wants to be pid1.

u-root init itself seems to be too complicated to configure as a
chainloader, so instead, we just provide init/pid1 ourselves and do the
little bit of mount setup / stage 1 that's necessary.

`tvix.exec` is renamed to `tvix.run`, to further distinguish it from the
`exec` bash function.

Our init will now also power off the machine if the shell, or the custom
tvix.run command finished. In the case of switch_root (`init=` being
passed), we terminate before, so it's up to the real system anyways.

ba3edc5638 feat(tvix/tests): add basic plumbing for integration tests
This adds a basic skeleton to test various tvix components in
combination.

As a first start, we test the virtiofs integration, by seeding the tvix-
store with some data, booting a VM, and listing the contents from there.
