[PATCH] tools: mark start-vmm test as requiring KVM

[PATCH] tools: mark start-vmm test as requiring KVM

[Alyssa Ross]

This will tell Nix (on a correctly configured system) that if it
doesn't have KVM, it can't build the package, allowing it to fall back
to outsourcing it to a remote builder in that case.

Ideally, we don't want to have any part of the Spectrum build
requiring KVM, but until that's fixed, occurences should at least be
correctly marked.

Fixes: a4e3a40 ("host/start-vmm: actually run "run" test")

Demi, if you find other occurences of derivations requiring KVM to build,
please send a patch like this. :)
