  1. tests/containers-imperative: Disable useSandbox 

    Since 4f6df27, nix.useSandbox defaults
to true which causes the Nix build within the containers-imperative test
to fail while trying to hardlink files into the chroot:

link("/nix/store/foo", "/nix/store/bar.drv.chroot/nix/store/foo")
   = -1 EPERM (Operation not permitted)

The reason this happens is that the hosts store is mounted using 9p and
an overlayfs is mounted on top, so even if we would disable the tmpfs
for the upper directory the hardlink would still cross filesystem
boundaries, which then fails with the above error code.

I haven't yet seen any other test which fails in a similar way, which
might be because building within VM tests is not very common and the
installer tests build in a separate store, so they're not affected.
