Trying to use search_and_kill_copytool() and search_copytools() functions to develop new sub-tests in sanity-hsm suite, found that copytool death delays were not handled and that this can be uniformized with what is done already in copytool_cleanup().

More sanity-hsm cleanup could also be to have both copytool_[setup,cleanup] use the same argument type, ie facetor host.
