Add support for running ART tests on a Linux virtual machine.

Test: setup a local VM and run ART tests on it:
  lunch aosp_arm64-userdebug

  export ART_TEST_SSH_USER=ubuntu
  export ART_TEST_SSH_HOST=localhost
  export ART_TEST_SSH_PORT=10001
  export ART_TEST_ON_VM=true

  . art/tools/buildbot-utils.sh
  art/tools/buildbot-build.sh --target

  # Create, boot and configure the VM.
  art/tools/buildbot-vm.sh create
  art/tools/buildbot-vm.sh boot
  art/tools/buildbot-vm.sh setup-ssh  # password: 'ubuntu'

  art/tools/buildbot-cleanup-device.sh
  art/tools/buildbot-setup-device.sh
  art/tools/buildbot-sync.sh

  art/test.py --target -r 001-HelloWorld
  art/tools/run-gtests.sh

Test: check that non-VM testing still works:
  lunch aosp_arm32-userdebug

  . art/tools/buildbot-utils.sh
  art/tools/buildbot-build.sh --target

  export ART_TEST_CHROOT=/data/local/art-test-chroot

  art/tools/buildbot-cleanup-device.sh
  art/tools/buildbot-setup-device.sh
  art/tools/buildbot-sync.sh

  art/test.py --target -r --32 001-HelloWorld
