[PATCH 2/2] scripts/device-crash-test: Add a parameter to run with TCG only

[Thomas Huth <thuth@redhat.com>]

We're currently facing the problem that the device-crash-test script
runs twice as long in the CI when a runner supports KVM - which sometimes
results in a timeout of the CI job. To get a more deterministic runtime
here, add an option to the script that allows to run it with TCG only.
